HOLOGRAPHIC ACCESS CONTROL

Description

[0001] The invention relates to a system for a functionalized door pane through which person- and / or object-related authorization control can be carried out. For person-related control, at least one holographically based, stereoscopic Holocam, which can be integrated into the pane, can be included. Furthermore, a holographic display, which can also be integrated into the pane, can be included.

[0002] Through appropriate procedures, the authorization check can be carried out in a controlled manner by the control device, and a door locking mechanism and a holographic display can be controlled. Background and state of the art:

[0003] Radio-based access control systems for vehicles are known to perform object-based authorization of a person using their key when the person enters the immediate vicinity of the vehicle. However, such systems are known to suffer from inherent security vulnerabilities. Therefore, two-factor authentication is advantageous for vehicles, as well as in other areas such as building doors. Two-factor authentication prevents access to the vehicle if the key is stolen or cloned. Unfortunately, such authentication is often very impractical, for example, if a password has to be entered every time access is granted. Therefore, identifying the person themselves, based on their visual characteristics (e.g., facial recognition), is preferable.However, it is often difficult to integrate the necessary camera optics into the door without compromising the space required for other desired components. Furthermore, such facial recognition systems can be easily fooled, for example, by displaying only a picture of the person instead of the person themselves. This problem can be solved, for instance, with three-dimensional facial recognition, but this increases the space requirement even further.

[0004] The possibilities of using holographic displays or holographic controls, for example to simplify authentication or door operation, make it more intuitive, or enable contactless operation, are also severely limited due to space constraints. Such a system is known, for example, from EP 3 002 736 A1. Often, these elements are also intended to be invisible for aesthetic or security reasons.

[0005] In particular, for practical reasons, doors are often to be fitted with large transparent surfaces such as windows, which, however, makes the use of the aforementioned functionalities and elements more difficult, as these typically cannot be accommodated in the window area. Purpose of the invention:

[0006] It is an object of the invention to provide a system, a door and / or a method without the disadvantages of the prior art.

[0007] In particular, an object of the invention is to provide a system or method that performs secure authorization control and is intuitive, simple, and hygienic to operate, without impairing the external appearance and transparency of a disc. Functionalized discs are known, for example, from DE 10 2019 102610 A1. Summary of the invention:

[0008] The problem is solved by the features of the independent claims. Preferred embodiments of the invention are described in the dependent claims.

[0009] In a first aspect, the invention relates to a system for a door opening control of a door or a flap with a functionalized disc, comprising a transparent base body with a front and a back for the functionalized disc, at least one holographic camera for a stereoscopic image recording of a defined detection area opposite the front and / or the back of the transparent base body and a control device.

[0010] The holographic camera has at least one recording hologram enclosed by the base body for deflecting light beams from the detection area. Furthermore, the camera and the control unit are configured for person-specific authorization control of a person captured by the stereoscopic image, wherein the person-specific authorization control is based on at least one characteristic of the person that can be determined by the stereoscopic image. The control unit is configured to output an unlock signal for opening the door upon at least one person-specific authorization.

[0011] The at least one holographic camera for stereoscopic image acquisition of a defined detection area opposite the front and / or the back of the transparent base body preferably describes at least one holographic camera for stereoscopic image acquisition of a defined detection area, which may be located opposite the front and / or the back of the transparent base body.

[0012] The fact that the holographic camera has at least one receiving hologram encompassed by the base body for deflecting light beams from the detection area preferably means that the system has at least one receiving hologram arranged in or on the base body for deflecting light beams from the detection area for the holographic camera. This receiving hologram can, but need not, be considered a component of the holographic camera; it can also be a component of a holographic camera system.

[0013] Deflection of light rays for the camera is specifically a deflection of light rays so that they can be detected by the camera.

[0014] A person skilled in the art does not interpret terms like "system" to mean that all components encompassed by the system are separate components. One component can, for example, encompass another component. Rather, the term "system" is to be understood as referring to components that preferably comprise a device with at least one component intended for installation in, for example, a vehicle or a consumer product. The functionality of the system, enabled by its features, is advantageously made possible by the installation. The system components can be installed in different locations or in the same location; what is important is that the system's features can interact as described after installation. The system can be installed from the outset, or it may be possible to install the system at a later time on the desired product or device.to retrofit the object. Since such a retrofit kit should also be covered by the claims, and since the system should also be claimed independently of the product or object in which it is installed, a system was claimed here.

[0015] A door opening control system for a door or hatch with a functionalized panel specifically concerns the opening process of a locked door. This door opening control system can, for example, be used for access control of a room, building, vehicle, or device enclosed by the door.

[0016] A door can be, for example, a vehicle door, a building door, a room door, a refrigerator door, an oven door, a washing machine door, a dryer door, and / or a freezer door. A washing machine door or dryer door can also be called a loading hatch. It can be an interior door and / or an exterior door. It can also be a flap, such as a vehicle's trunk lid, a vehicle's fuel filler cap, etc. When this document refers to a door, it preferably includes all doors, flaps, lids, etc., listed herein.

[0017] A door opening control for a door or flap with a functionalized disc preferably describes a door opening control for a door or flap, wherein the door opening control has a functionalized disc or functions in conjunction with the functionalized disc. This functionalized disc can be part of the door or flap, but it can also be arranged outside the door or flap, e.g., next to it.

[0018] A door opening control for a door or flap with a functionalized pane can, in some cases, also describe a door opening control for a door or flap where the door or flap itself features the functionalized pane. The functionalized pane is then preferably a solid, particularly a materially dense, but more preferably transparent part of the door or flap. For example, it could be a window pane.

[0019] For example, the flap can also be a fuel tank cap, wherein the functionalized disc is part of the fuel tank cap, is preferably opaque, and the planar base body is applied to the disc and enables the functionality.

[0020] The functionalized disc is made of, for example, glass or transparent plastic.

[0021] Preferably, the functionalized disc is a planar element.

[0022] However, it could also be an essentially opaque pane, or a pane that is sufficiently transparent to enable the functionality but appears opaque from the outside, especially if it is applied to an opaque surface. For example, it could be a tinted pane.

[0023] Functionalized means, in particular, that the disc can be used for a function, especially as described in this document. For example, the disc can be used for a camera as described here or a display as described here.

[0024] A functionalized disc can, in particular, be a planar element with the desired optical or aesthetic properties. A functionalized disc can, in particular, comprise a substrate.

[0025] The transparent base body, with a front and a back side for the functionalized discs, can, for example, be part of the functionalized disc. In some cases, the transparent base body can even constitute the functionalized disc itself.

[0026] However, the transparent base body can also be applied to the functionalized disc, for example, in the form of at least one layer. Preferably, the transparent base body enables the functionality.

[0027] The transparent base body can, in particular, be a substrate.

[0028] Transparent preferably means that one can see through the base body. In particular, transparent means that the base body has a transmittance, relative to the intensity of the light (preferably in a wavelength range between 420 nm and 750 nm), of at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90% and / or at least 95%.

[0029] However, "transparent" can also mean that the base body exhibits the transparency described above only for a smaller wavelength range within the larger range mentioned, e.g., for a range of 100 nm or less, 50 nm or less, or 20 nm or less within the wavelength range between 420 nm and 750 nm. The smaller wavelength range is specifically selected to enable the functionality of the invention described herein.

[0030] The base body can be sufficiently transparent to enable the desired optical functionality, but appear opaque from the outside, especially when applied to an opaque surface. It could, for example, be a tinted base body.

[0031] Preferably, the transparent base body is a planar, transparent base body. Planar in this context means, in particular, forming a wider surface, being flattened, and / or extending over a surface. Planar can, for example, mean that the base body has a large extent along a plane or surface and a comparatively much smaller extent in a perpendicular direction. The plane or surface can also be curved. A comparatively smaller extent preferably means an extent that is at least twice as small as the smallest extent along the surface or plane.

[0032] The transparent base body can be equipped with a functionalized waveguide for a detector system, as described in WO 2020 / 157306 A1, WO 2020 / 157307 A1, WO 2020 / 157308 A1, WO 2020 / 157309 A1, WO 2020 / 157310 A1, WO 2020 / 157311 A1, WO 2020 / 157312 A1 and / or WO 2020 / 157313 A1.

[0033] The recording hologram may preferably comprise a transmissive and / or reflective hologram.

[0034] A holographic camera (holocam) is preferably a camera configured to capture an image of radiation striking the front or back of a transparent base body, preferably without significantly affecting the transparency of the base body when looking through it. This can be achieved, for example, by a holographic and / or diffractive structure that deflects a portion of the radiation, e.g., onto a suitable image sensor for image capture, either directly or by using at least one further diffractive and / or holographic structure.

[0035] Holographic cameras are state of the art and are sufficiently described in the aforementioned publications, so that a specialist knows how to implement a corresponding holographic camera.

[0036] Therefore, the expert also knows how to implement at least one holographic camera for stereoscopic image recording of a defined detection area opposite the front and / or the back of the transparent base body.

[0037] At least one holographic camera for stereoscopic image acquisition preferably comprises two holographic cameras for stereoscopic image acquisition. In particular, the images from the two holographic cameras are used and / or combined for stereoscopic image acquisition.

[0038] At least one holographic camera for stereoscopic image acquisition can preferably be a holographic camera system for stereoscopic image acquisition. A holographic camera system can comprise one or more of the following components: a holographic camera, an image sensor, and / or a recording hologram, which enable the system to be suitable for stereoscopic image acquisition.

[0039] It can also include two holographic camera systems for a front and a back, e.g., comprising a total of at least four holographic cameras, e.g., to create a recording from a door for an indoor and an outdoor area.

[0040] Preferably, the detection area describes a spatial area from which the light rays used for image acquisition originate or which these light rays have passed through before striking the front or back of the base body.

[0041] For example, a person skilled in the art could use two individual holocams for stereoscopic image acquisition, as described in this document and in the aforementioned publications. They could then combine the captured or deflected radiation, or the image material derived from that radiation, in such a way as to obtain a stereoscopic image. It may also be preferable to use three or more holographic cameras.

[0042] Stereoscopic preferably means that an image is captured from two different, preferably adjacent, locations to record at least one object from preferably two slightly different viewing angles. In this way, spatial depth information can be obtained from the recording, and additional information can advantageously be captured along with the object by recording it from the different angles. A stereoscopic recording is preferably comparable to the viewing of at least one object by a pair of eyes. Due to the distance between the eyes and the resulting slightly different viewing angles, the viewer can gain spatial information, such as the approximate distance of the object or its spatial shape.Preferably, a stereoscopic image acquisition comprises the acquisition of two images, preferably from different, particularly adjacent, locations. The adjacent locations can be realized, in particular, by including two lenses. These can, for example, be partially realized by two recording holograms or by a recording hologram with two recording areas. It may be preferred to acquire these images simultaneously, preferably using two image sensors. However, it may also be preferred to acquire the images from two different locations alternately at a high frequency, for example, with only one image sensor. A high frequency can be achieved, for example, by...The frequency should be at least 50 Hz and should be selected such that a moving person being recorded can be considered essentially stationary for two alternating recordings, for the purposes intended here. This can be achieved, for example, by an adjustable polarization filter switched at the appropriate frequency, wherein the holograms used for the respective recordings preferably have corresponding polarizations that can be filtered out by the filter.

[0043] However, it may also be preferable to achieve the different perspectives for stereoscopic imaging by using only one camera and / or a recording hologram, provided the person being imaged has to move—for example, for facial recognition, turning their head left and / or right—to capture the different perspectives in a relatively short sequence. This could be a particularly simple way to implement stereoscopic imaging, but it does require compromises in security compared to capturing the person from different perspectives simultaneously. However, if the sequence of images is sufficiently high, a high level of security can still be achieved.

[0044] An image recording may preferably consist of a single image, but may preferably also consist of a series of images and, in particular, a video recording depicting moving images.

[0045] A typical distance between adjacent locations from which stereoscopic imaging is performed can roughly correspond to the distance between the eyes and be, for example, between 50 and 80 millimeters (mm). However, other distances can also be used, preferably in a range between 10 mm and 1 meter (m).

[0046] In particular, stereoscopic imaging can distinguish whether the structures observed during the image capture are three-dimensional, i.e., have different distances to the viewer, or are merely two-dimensional structures within a plane. For example, it is possible to differentiate between a photograph of a face and an actual face with a three-dimensional surface.

[0047] Preferably, stereoscopic image capture is designed to distinguish persons based on their recognizable features, especially their facial features, or to categorize them based on specific characteristics, with particular emphasis on three-dimensional features. In particular, stereoscopic image capture is suitable for three-dimensional facial recognition, motion detection, and / or iris recognition.

[0048] Motion detection can be performed independently or in addition to facial and / or iris recognition and may, for example, include specific predefined movements, which can also be user-specific and / or customizable. For instance, it may be preferred that a vehicle door or a front door can only be opened by a specific movement, particularly a dance move, which a user has preferably specified to the system.

[0049] Even with iris recognition, stereoscopic imaging can preferably increase the security of authorization checks, particularly due to the different viewing angles. This allows, for example, better compensation for shadows caused by the frames of glasses for people who wear them.

[0050] Preferably, the at least one holographic camera used for stereoscopic image capture can also be used to take "normal," non-stereoscopic images. For example, facial recognition can be performed in three dimensions, and iris recognition can be performed in two dimensions using at least one additional camera. This further enhances security.

[0051] It may also be preferable to recognize specific objects. This may preferably also include person-based authorization control. Object recognition can preferably be improved by stereoscopic image acquisition. For example, a system integrated into a fuel filler cap can detect whether the nozzle is being used for the correct fuel, e.g., diesel or premium gasoline.

[0052] A control device is, in particular, at least one integrated circuit, e.g., at least one microprocessor, at least one processor or processor unit, at least one CPU, at least one computer, and / or at least one computer. A control device may, for example, comprise an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA). Furthermore, it may include components known to those skilled in the art, such as at least one integrated circuit, at least one digital-to-analog converter, at least one analog-to-digital converter, and / or at least one amplifier.

[0053] The holographic camera has at least one receiving hologram enclosed by the base body for deflecting light rays from the detection area. The receiving hologram is preferably suitable for deflecting at least a portion of the light rays from the detection area so that they can be used for image acquisition. For example, the light rays can be deflected onto a detector, e.g., in the form of an image sensor.

[0054] The recording hologram is preferably a diffractive structure. Preferably, the terms holographic and diffractive, or hologram and diffractive element, can be used synonymously in this document.

[0055] The recording hologram preferably deflects at least a portion of the light from the detection area such that the light is redirected for image capture. The recording hologram can comprise several holograms, e.g., at least two. It can be a single hologram configured to capture light from two locations for the two stereoscopic images required. Preferably, however, it can also be two separate recording holograms.

[0056] The recording hologram can preferably be considered analogous to a lens or part of a lens of a "classic" camera, wherein the recording hologram collects and / or deflects the light to be recorded. It may be preferred that the recording hologram also exhibits beam-shaping properties.

[0057] The detection area can preferably be selected according to the specific application of the system, e.g., during the production of the hologram. For example, if the system is integrated into a car's side door and the functionalized pane is its side window, preferably encompassing the base unit, then the detection area can preferably be selected such that the face of an average-sized person standing at a distance from the side door suitable for manually opening the door from that position (e.g., at a distance of less than 1 meter (m), preferably less than 0.6 m from the side door) is deflected by the recording hologram. The detection area is preferably a sufficiently large volume so that the faces of people of varying heights can be used for person-specific authorization control within a practically large distance range from the base unit.On the one hand, the recording hologram can deflect light from a sufficiently large angular range or angular spectrum; on the other hand, the control device can also contribute to increasing the detection range if necessary by appropriately post-processing the data from the image recording, taking distortions, blurring or other optical effects into account during authorization control.

[0058] The detection area is preferably the area from which the radiation emanating from an object to be detected and striking the front and / or back of the base body originates. The receiving hologram can be configured, in particular, to deflect radiation striking the base body perpendicularly. However, it can also be optimized for other angles, for example, if the desired detection area is offset above, below, and / or laterally, and / or if the disk encompassing the base body is inclined. The receiving hologram can also have a beam-shaping function, such as a collimating function, and / or can take into account the curvature of a disk encompassing the base body.

[0059] The recording hologram is preferably substantially or at least partially transparent, so that the base body is substantially or at least partially transparent at the location where the hologram is arranged.

[0060] Preferably, the recording hologram deflects light from at least one spectral range. This spectral range can be narrow, for example, on the order of 1 nanometer (nm) when converted to wavelength, but it can also be on the order of 10 nm or 100 nm or more.

[0061] Terms such as "essentially", "approximately", "about", "approximately", etc. preferably describe a tolerance range of less than ± 20%, preferably less than ± 10%, even more preferably less than ± 5%, and particularly less than ± 1%. Statements using "essentially", "approximately", "about", etc., always disclose and include the exact value stated.

[0062] The recording hologram can be configured to deflect different angular spectra and / or spectral ranges. For example, the recording hologram can comprise multiple holograms, each deflecting a different angular spectrum and / or spectral range. These holograms can be arranged one above the other, particularly in a stack, in a so-called stack.

[0063] In an alternative embodiment, the hologram components assigned to the respective angular spectra and / or spectral ranges are contained in a single recording hologram, in particular in a so-called holographic film, in which they were exposed together. Such a recording hologram is preferably also referred to as a multiplex hologram.

[0064] The area containing the receiving hologram is preferably also referred to as the coupling area, and the receiving hologram as a diffractive structure. This is a particularly appropriate term when the light radiation from the detection area is coupled into the base body for further light guidance within the base body.

[0065] The transparency of the recording hologram and / or the coupling area is primarily dependent on the efficiency of the radiation coupling and / or the efficiency of the deflection of the light beams. With increasing coupling efficiency and / or deflection efficiency, the transparency in the coupling area and / or the recording hologram also decreases.

[0066] To achieve maximum transparency, the deflection and / or radiation coupling by, for example, the diffractive structure (especially the at least one volume hologram) can be just efficient enough to ensure sufficient radiation power reaches the output coupling area. The partially transparent input coupling area can be designed such that the input efficiency and / or the deflection efficiency is, for example, 2%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, or 50%. This efficiency is preferably related to the portion of the spectrum deflected by the receiving hologram. However, it can also be related to the entire visible frequency spectrum of light. In particular, the input efficiency can be in the range of 2% to 50%, resulting in a transparency of the input area in the range of 50% to 98%.

[0067] In this document, "holographic" is preferably used synonymously with "diffractive." In particular, a holographic element, e.g., a hologram, is characterized by a manufacturing method using exposure adapted to the desired diffraction, for example, with a corresponding reference and object wave. Computer-generated holograms, whose computer-aided calculation is based on holographic principles, can also preferably be included.

[0068] The camera and control unit are configured for person-specific authorization verification of a person captured by stereoscopic imaging. Person-specific authorization verification is preferably one that enables authorization using the person being authorized and their attributes. Verification preferably means checking whether authorization exists. The person preferably does not need to carry any item, such as a key or document, for identification.

[0069] The fact that the camera and control unit are configured for person-specific authorization control as described here means that appropriate means, known to those skilled in the art, are available to perform this control. For example, the camera can provide a preferably electrical output signal, which is fed to the control unit, e.g., via signal lines. The control unit then has appropriate means, e.g., at least one processor and at least one data storage device, with which the control is carried out. For this purpose, a suitable algorithm, e.g., a recognition algorithm, can be used, which is implemented by the control unit.

[0070] The person-specific authorization control is preferably carried out based on previously learned and / or predefined characteristics. For example, there can be a learning mode in which further faces are added for facial recognition.

[0071] Person-based authorization control is based on at least one characteristic of the person that can be determined through stereoscopic imaging. A characteristic of the person that can be determined through stereoscopic imaging can be a two-dimensional characteristic lying in a (two-dimensional) plane, and in particular a three-dimensional characteristic of the person. Specifically, the characteristic of the person can include their facial features.

[0072] Authorization control is preferably also referred to as authentication, with authorization also being referred to as authentication.

[0073] Preferably, the authorization control described here includes facial recognition, in particular 3D facial recognition.

[0074] For example, the following steps can be implemented, in particular through the control device and the algorithm it implements: Recognizing and extracting the facial image from the background. Aligning the facial image to take into account, for example, facial position, image size, and other image properties such as lighting and grayscale. This preferably facilitates the localization of facial features. Localization of facial features (facial feature extraction). The facial features preferably include the eyes, nose, and / or mouth. The facial features are preferably located and measured within the image to represent the face and determine a so-called feature vector of the face. Comparing the facial features and / or the feature vector with known faces, facial features, and / or feature vectors, which are stored, for example, in a database.

[0075] The following are just a few preferred facial recognition algorithms: Identification of facial features by extracting landmarks and / or features from a facial image, e.g., analyzing the relative position, size, and / or shape of the eyes, nose, cheekbones, and / or jaw, and using these features to search for facial images with matching features. Normalizing a gallery of facial images, compressing the facial data so that only data useful for facial recognition is stored in the image, and comparing a specific facial image with the facial data. For example, the algorithm can be based on template-matching techniques known to those skilled in the art.

[0076] Recognition algorithms can include, for example, geometric recognition algorithms. These preferably deal with facial features as described.

[0077] Recognition algorithms can also include photometric recognition algorithms. These preferably employ a statistical approach, where the image is advantageously divided into values ​​and the values ​​are compared with templates to eliminate / detect deviations.

[0078] Recognition algorithms can also include holistic recognition algorithms, in which the face should preferably be recognizable in its entirety.

[0079] Recognition algorithms can also include feature-based recognition algorithms. These preferably divide the face into components and / or features and analyze these, as well as preferably their spatial position relative to each other.

[0080] The at least one recognition algorithm preferably comprises at least one algorithm selected from the group including principal component analysis using eigenfaces, linear discriminant analysis, elastic bunch graph matching using the Fisherface algorithm, hidden Markov model, multilinear subspace learning using the tensor representation and / or neurally motivated dynamic link matching.

[0081] It may preferably include a so-called facial hallucination algorithm. These algorithms can advantageously facilitate facial recognition in environments with a high signal-to-noise ratio and are preferably used before the actual recognition algorithm. Such an algorithm preferably employs example-based machine learning with pixel substitution and / or nearest-neighbor indices. Demographic and / or age-related facial features can preferably be included. Advantageously, with appropriate training data, such algorithms can also detect partially covered faces.

[0082] A preferred three-dimensional face recognition method is preferably based on image captures containing information about the shape of a face, in particular a stereoscopic image. This information can be used, for example, to detect and / or identify distinctive facial features, especially on the surface of the face, such as the contours of the eye sockets, nose, and / or chin. Advantageously, 3D face recognition is not affected by changes in lighting. Furthermore, a face can advantageously be identified from different viewpoints, such as a profile view, and the precision of the face recognition can be improved. Matching techniques, in particular metric geometry, can preferably be used for 3D face recognition, for example, to treat expressions as isometric projections.

[0083] 3D facial recognition can, in particular, prevent authorization checks from being fooled by a two-dimensional photograph of a person's face instead of the person's actual face.

[0084] Authorization preferably means the granting of rights based on a successful verification of predefined criteria. These criteria may, for example, relate to one or more personal identities, membership in a group of people, and / or the possession, carrying, and / or use of a specific object. A person-specific authorization preferably includes authorization based on one or more personal identities and / or membership in a group of people. In this context, granting rights means, in particular, at least a partial granting of the right to open the door. "At least a partial right" in this context means that the right to open can be based on more than one authorization, with the person-specific authorization being one of these multiple authorizations.Personal authorization can occur in particular if the face of an authorized (preferably authorized) person is within the detection range and is recognized based on at least one characteristic of the person, particularly in their face, that can be determined by the stereoscopic image recording.

[0085] The control unit is configured to output an unlocking signal for opening the door upon at least one person's authorization. This unlocking signal is specifically a signal that can then be sent to a locking component, which in turn unlocks the door. An unlocking signal can, for example, comprise an electrical signal and / or an optical signal. Thus, after authorization—preferably the granting of corresponding rights—the control unit effectively outputs a corresponding signal, which, in combination with other elements, enables the door to be opened, thereby giving practical effect to the initially theoretical granting of rights.

[0086] The control device is specifically designed to issue an unlocking signal for opening the door only with at least one person-specific authorization and not otherwise.

[0087] The control device may preferably be configured to issue a locking signal for closing the door, or to continue to issue such a signal even if no personal authorization is given.

[0088] It may be advantageous for the system to be configured to simultaneously project light, particularly structured light (e.g., a grid pattern to facilitate facial recognition), for example in the infrared range, into the detection area and especially onto the face. This can advantageously improve three-dimensional facial recognition. The projection can be performed, for example, by a suitable light source and a projection hologram encompassed by the base body.

[0089] The described system can increase the security and reliability of authorization checks by using a control mechanism based on a person's characteristics as determined through stereoscopic imaging. For example, authorization can be advantageously prevented by a two-dimensional image of a person's characteristics, thus avoiding deception. Furthermore, authorization can be implemented even under challenging optical conditions because the stereoscopic imaging enhances reliability, which is also based on a degree of data redundancy and / or the increased information content of the image due to the different viewing angles. Simultaneously, the holographic camera allows for image capture from within the transparent base unit.This allows for the creation of a functionalized pane of glass that, in addition to being transparent, can also function as a camera. It enables a camera position for image capture that would otherwise be impossible, as glass panes are not typically designed in this way. Particularly in certain applications, such as car doors, the camera position in the side window, which can be advantageously implemented, is ideal for person-based authorization control. This is because a person opening a door typically positions themselves in front of the window, within a horizontal plane. A direct view through a transparent, invisible camera can be captured.The camera can be implemented "invisibly" using the method described here, thus offering an additional security feature by, for example, recording authorized individuals attempting to open the door. The Holocam can, for instance, provide a kind of peephole and surveillance security function for the exterior of the room. This "invisible" implementation can also be advantageous from an aesthetic point of view. Furthermore, the functionalized window can be larger because no additional space needs to be created for the camera. This can, for example, increase security in a vehicle.

[0090] In a further preferred embodiment of the invention, the system further comprises a first communication means for sending and receiving signals, wherein the first communication means and control device are configured for object-related authorization control of an associated second communication means for sending and receiving signals, particularly when the latter is located in the sending and receiving range of the first communication means.The object-based authorization control is based on the position and / or movement of the second communication device in relation to a predetermined proximity of the first communication device, as well as on the properties of signals exchanged between the first and second communication devices, whereby the control device is configured to output an unlocking signal for opening the door in the case of person-based authorization and object-based authorization of the second communication device.

[0091] The signals to be sent and received can be, for example, electromagnetic signals, in particular optical signals, infrared signals and / or other signals for wireless transmission, e.g. radio waves, in particular long waves, medium waves, short waves and ultra-short waves, radar and / or microwaves.

[0092] The first communication means for sending and receiving signals can, for example, comprise a transceiver for radio waves and / or optical signals and / or a wireless communication interface. It can include at least one antenna for transmitting and / or receiving electromagnetic signals. Furthermore, the first communication means can include components known to those skilled in the art in this field, such as at least one integrated circuit, at least one digital-to-analog converter, at least one analog-to-digital converter, and / or at least one amplifier.

[0093] The second means of communication may preferably also include the components mentioned in connection with the first means of communication.

[0094] The first and second means of communication can be based on NFC and / or RFID technologies, for example.

[0095] The first communication device and the control unit are set up for object-related authorization control of an assigned, second communication device for sending and receiving signals.

[0096] Object-based authorization control preferably refers to an authorization control that is based on verifying the presence, possession, and / or use of a specific, authorized object. This object could, for example, be a key that serves as the second means of communication.

[0097] The second communication means is preferably at least one second communication means. An associated second communication means for sending and receiving signals is preferably suitable for communicating with the first communication means and, in particular, for receiving its signals and sending signals to it. This is preferably encompassed by the term "associated." "Associated" advantageously further means that there can be a plurality of second communication means suitable for communicating with the first communication means and, in particular, for receiving its signals and sending signals to it, wherein, however, only a subset of second communication means, preferably fewer than 10, more preferably fewer than 5, and especially fewer than 3, can actually lead to authorization during the authorization check.These are also referred to as authorized secondary means of communication. For example, several keys can comprise a secondary means of communication, which exchanges signals with the primary means of communication, but only one key and one backup key are assigned in the sense that they can lead to object-specific authorization.

[0098] Object-based authorization preferably includes authorization based on the presence, possession, and / or use of a specific object, e.g., an assigned key.

[0099] Object-based authorization control relies on the position and / or movement of the second communication device relative to a predefined proximity of the first communication device, as well as on the properties of signals exchanged between the first and second communication devices. Object-based authorization control therefore preferably comprises two control steps: first, it is checked whether the second communication device (and preferably the object encompassing it) is, for example, within the predefined proximity of the first communication device. Second, based on the exchanged signals, it is preferably checked whether the second communication device is the authorized second communication device.

[0100] A predefined immediate area is preferably defined as a spatial area that is uniquely definable with respect to the first communication means and / or its components. A spatial area can, for example, encompass a volume. "With respect to the first communication means" preferably means "with respect to the first communication means" if it is enclosed within a door. For example, the spatial area can be uniquely defined with respect to the door and / or the first communication means with respect to its dimensions in the various spatial directions, as well as with respect to the reference point from which these dimensions are determined. There can preferably be minimum and maximum dimensions. The reference point is preferably uniquely determined with respect to the door and / or the first communication means.For example, the first communication device can be configured and installed in the door such that the immediate area is located on one side of the door and encompasses a certain "box" or spherical cutout with respect to a reference point enclosed by the door. As an example, the immediate area is chosen to encompass only the exterior of the vehicle opposite the door and includes at least one area at a distance of one meter from the exterior of the door, as well as all areas within one meter of the outer edges of the door. It is advantageous to define the immediate area preferably with respect to a door in which the system is installed; however, it is clear to those skilled in the art that even then, it is ultimately advantageous to define the immediate area with respect to the first communication device and its components, since these are preferably permanently installed in the door.Preferably, a reference point can be defined on the first communication means, with the short range defined relative to it. A defined short range of the first communication means is then preferably a defined short range relative to this reference point. For example, the reference point can be the location of the transmitting and / or receiving component, or, in the case of multiple transmitting and / or receiving components, the geometric center of gravity of the multiple transmitting and / or receiving components.

[0101] Preferably, the near area can be arranged isotropically with respect to the first communication means. It is equally preferred that the near area be defined differently with respect to the directions viewed from the first communication means. For example, the near area can comprise a half-space subdivided by the door, as described above.

[0102] Preferably, the near area is at least one near area. Preferably, several near areas can be included, between which a distinction can be made. If the door is, for example, an exterior door, a distinction can preferably be made between the interior area "behind the door" and the exterior area "in front of the door," and, for example, authorization can be performed only in one case and not in the other. Thus, depending on the embodiment, for example, an unlocking signal, a holographic display, and / or the Holocam can be output only in one case and not in the other.

[0103] An object-based authorization control, which relies on the position of the second communication device relative to the predefined proximity area, preferably requires, as a necessary criterion for object-based authorization, that the second communication device be located within the predefined proximity area. Preferably, the object-based authorization is therefore at least partially based on the position of the second communication device within the predefined proximity area of ​​the first communication device. This can be achieved, for example, by a predefined minimum signal strength between the first and second communication devices and / or a signal-based localization mechanism, such as one based on triangulation.

[0104] An object-based authorization control, which relies on the movement of the second communication device in relation to the predefined immediate area, can, for example, have as a necessary or additional necessary criterion that the second communication device moves closer to and / or further away from the first communication device and its immediate area. This can be determined, for instance, by an increasing and / or decreasing signal strength between the first and second communication devices. It may also be preferable that specific movement patterns of the second communication device must be executed within the immediate area as a necessary criterion for object-based authorization. For example, user-specific, individual movements can be performed, which, for instance, have been previously "taught" to the system in a learning mode.

[0105] Object-based authorization control relies not only on the position and / or movement of the second communication means in relation to a predetermined proximity of the first communication means, but also on properties of signals exchanged between the first and second communication means. This preferably means that the signals exchanged between the two communication means can be used to determine whether the second communication means is authorized. Those skilled in the art are aware of corresponding authentication methods, for example, based on a secret shared between the first and second communication means and / or cryptographic encryption and authentication methods.

[0106] The control unit is configured to issue an unlock signal for opening the door upon personal authorization and object-based authorization via the second communication device. This allows for increased security through two-factor authentication.

[0107] The following describes a possible embodiment of this system. The first communication device can, for example, transmit a coded request signal, such as an electromagnetic signal, particularly with an LF frequency of 125 or 130 kHz, via at least one antenna (e.g., either on its own or triggered by an event). The first communication device is then ready to receive, for example, in the UHF range (e.g., 433 MHz, 868 MHz, and / or 315 MHz). It is ready to receive an acknowledgment transmitted by the second communication device. When the second communication device is within range, it receives the signal, for example, at 125 kHz, decodes it, and then retransmits this signal with a new encoding, for example, in the UHF frequency band.The signal received by the first communication device is then decoded by it (and / or the control device), since the first and second communication devices are advantageously configured to perform this encoding. Corresponding encoding methods are known to those skilled in the art. Thus, the signal originally transmitted by the first communication device can preferably be compared with the signal received by the second communication device. If no response is received within a defined time that meets certain comparison criteria, no unlock signal is generated. For example, the system then switches (back) to a standby mode. However, if the signals match or meet certain comparison criteria, this preferably results in authorization and an unlock signal is generated.

[0108] In a further preferred embodiment of the invention, the control device is configured to enable person-specific authorization only after object-based authorization has been performed. This is a particularly advantageous embodiment of two-factor authorization, in which the simpler and less secure object-based authorization check is performed first, followed by the more complex, energy-intensive, and secure person-specific authorization check. Preferably, the predefined immediate area is larger and / or further away from the system and / or the door than the detection area. Therefore, this embodiment is also advantageously particularly efficient from this perspective.

[0109] In a further preferred embodiment of the invention, a locking component is included which is configured for locking or unlocking the door, wherein the locking component is configured for unlocking the door upon output of the unlocking signal by the control device. A locking component can, in particular, comprise a lock for a door and / or an adjustable bolt for a door lock. The bolt is preferably in an extended position for locking and can be moved to a retracted position for unlocking.

[0110] In a further preferred embodiment of the invention, an operating component is included which is configured for the operation of the door by a person. Operating the door preferably refers to opening the door and / or a partial step necessary for opening the door, particularly in the case of an unlocked door. An operating component can, in particular, include a door handle or a component corresponding to the functionality of a door handle.

[0111] Those skilled in the art know that this may also include all meaningful combinations of the embodiments described herein, for example, an embodiment comprising both an operating component as described herein and a locking component as described herein. This naturally also applies to other aspects of the invention described herein.

[0112] In a further preferred embodiment of the invention, the operating component is configured to be activated upon the release signal being issued by the control device. Activation of the operating component particularly includes a process step necessary to enable subsequent operation. For example, a door handle can be released and / or extended upon activation to allow operation. If the operating component is a switch, it can also be released and / or illuminated upon activation.

[0113] In a further preferred embodiment of the invention, the operating component comprises a proximity and / or motion sensor based on ultrasound, an optical sensor, a wireless communication interface, and / or radar. This enables contactless operation by approach, movement, and / or gesture. Preferably, such an operating component is activated by outputting the unlock signal, since operation should only be possible after authorization has taken place. In this way, contactless operation can be achieved.

[0114] In a further preferred embodiment of the invention, the operating component comprises at least one capacitive sensor. Capacitive sensors are known, for example, from touchscreens and function particularly simply and reliably.

[0115] In a further preferred embodiment of the invention, the operating component comprises a holographically based operating component. A so-called holographic button is based, in particular, on the principle that a button can be displayed three-dimensionally and, in particular, as "floating" independently of a door surface by using holograms, and that a gesture within the displayed area can also be transmitted to a detector by a corresponding hologram and thus detected. In this way, a particularly intuitive, contactless operation of the operating component can also be achieved. In particular, the holographic operating component can be implemented by at least one hologram in the transparent base body. The holographic camera can preferably also be used to detect an operating gesture.

[0116] In a further preferred embodiment of the invention, the system further comprises at least one first holographic display for a display of at least one image directed towards a person, preferably in a defined display area opposite the front and / or the back of the transparent base body.

[0117] A holographic display is, in particular, a display that is generated using a hologram, especially a display hologram. A holographic display can, in particular, create a three-dimensional impression and / or, due to the highly adjustable diffraction properties of holograms, enable very flexible display options.

[0118] Preferably, the defined display area describes a spatial area in which the image is to be viewed.

[0119] The holographic display can preferably be used to display the holographic control element, in particular the holographic button.

[0120] The display area can preferably be selected according to the specific application of the system, e.g., in the production of the hologram used. For example, if the system is integrated into a car's side door and the functionalized pane is its side window, preferably encompassing the base body, then the display area can preferably be selected so that it essentially or partially coincides with the detection area. It may also be preferred that the detection area encompasses the display area, with the display area being larger. For example, the display within the display area can indicate the location of the detection area. The display area is preferably a sufficiently large volume so that people of varying heights can see the display at a practically large distance from the system and / or the door encompassing the system.The display area can preferably also be referred to as the eyebox.

[0121] For example, the display of the authorization status can be implemented in a transparent area.

[0122] In a further preferred embodiment of the invention, the first holographic display or at least a second, encompassed holographic display is arranged to generate the display when illuminated by ambient light from the transparent base body.

[0123] For example, it may be preferred that the first holographic display generates the display using its own light source, while the second holographic display generates the display using ambient light.

[0124] Ambient light is, in particular, natural and / or artificial light that originates from the environment of the system and / or the door encompassing the system and is present independently of the system. Ambient light can, for example, include sunlight and / or street lighting. Ambient light is, in particular, light that does not originate from a light source encompassed by the system. A holographic display generated from ambient light is preferably also called a "passive" holographic display, and a display hologram used for the passive holographic display is called a "passive" display hologram.

[0125] In contrast, a holographic display which is created by illuminating a hologram with a light source or image generator is preferably called an active hologram.

[0126] A passive hologram, unlike an active hologram, preferably has no defined display area, since the illumination of the ambient light, which preferably has a broad spectral range and a large angular spectrum, makes it particularly impossible to limit the display to a specific area. Such a holographic display is particularly easy to implement, efficient, and requires little maintenance.

[0127] In a further preferred embodiment of the invention, a holographic display and control device are configured to generate the first display of the image upon a signal from a proximity sensor encompassed by the system, wherein the proximity sensor and the control device are configured to generate the signal upon detection of a person in the immediate vicinity of the system and / or the door. The proximity sensor can advantageously be implemented as described above.

[0128] Such a display can be generated, for example, by including a suitable hologram and a corresponding light source for illuminating the hologram. This light source is activated by the control unit upon detection, thus generating the display by illuminating the hologram. The hologram could, for instance, be a display hologram enclosed within a transparent base body.

[0129] In a further preferred embodiment of the invention, a holographic display and control device are provided to generate the first display of the image during object-related authorization and / or person-related authorization.

[0130] Such a display can be generated, for example, by including a suitable hologram and a corresponding light source for illuminating the hologram. This light source is controlled by the control unit upon appropriate authorization, in order to generate the display by illuminating the hologram. The hologram could, for instance, be a display hologram enclosed within a transparent base body.

[0131] A display hologram preferably contains the image information to be displayed. This information can be used, in particular, to generate a real and / or virtual image by diffraction and / or deflection of suitable light beams. The display hologram can be configured to deflect different angular spectra and / or spectral ranges. For example, the display hologram can comprise several holograms, each of which deflects an angular spectrum and / or a spectral range. These holograms can be arranged one above the other, in particular stacked on top of the other, in a so-called stack.

[0132] In an alternative embodiment, the hologram components assigned to the respective angular spectra and / or spectral ranges are present in a single display hologram, in particular in a so-called holographic film, in which they were exposed together. Such a display hologram is preferably also referred to as a multiplex hologram.

[0133] Such display holograms can, for example, also generate multicolored images, which may appear simultaneously depending on the lighting, the respective lighting color and / or the respective viewing angle.

[0134] For example, a display generated during object-based authorization can show the detection area for person-based authorization control.

[0135] A display generated during person-specific or person-specific and object-specific authorization can, for example, show an operating area of ​​the operating component.

[0136] This can make the system easier to use.

[0137] In a further preferred embodiment of the invention, the system comprises a light source for illuminating at least one first display hologram encompassed by the transparent base body for the first display upon input of a display signal, wherein the control device is configured to output the display signal to the light source during object-related authorization, person-related authorization and / or upon detection of a person in the vicinity of the system and / or the door, and wherein the display hologram and the light source are configured to generate the display of the image upon illumination, preferably of the display hologram, by the light source.

[0138] A light source can, for example, include an LED and / or a laser. The first display hologram contains the image information to be displayed, which, with appropriately calibrated illumination, generates the image. The light source is, in particular, such calibrated illumination. "Calibrated" can refer, for example, to the frequency spectrum, the angular spectrum, and the center-of-mass angle at which the illumination occurs, and / or the coherence of the light (spatially and / or temporally).

[0139] The fact that the display hologram and the light source are configured to generate the image display when illuminated by the light source preferably means, firstly, that the light source includes coordinated illumination and, secondly, that the light source and the display hologram are designed and positioned relative to each other in such a way that the light source can illuminate the display hologram at least partially. The light source may preferably include a beam-shaping component, e.g., a lens, to collimate the emitted light rays accordingly.Furthermore, this means that the light source and display hologram are matched with respect to the angular spectrum of the light rays incident on the display hologram, the center-of-mass angle of the light rays incident on the display hologram, the frequency spectrum of the light rays incident on the display hologram, and / or the coherence of the light rays incident on the display hologram. This allows the image information generated by the image sensor to be displayed particularly effectively by the display hologram.

[0140] A display signal is preferably a signal that causes the light source to be switched on. It can, in particular, be an electrical signal.

[0141] The light source can preferably comprise multiple LEDs and / or lasers to generate displays of varying brightness and / or color. The display signal can, for example, include multiple signals, which can preferably be generated independently of one another to achieve, for instance, an animated display.

[0142] In a further preferred embodiment of the invention, the system comprises an image generator for generating at least one projectable image upon input of an image generator signal and at least one projection hologram encompassed by the transparent base body for the first display, wherein the control device is configured to output the image generator signal to the image generator during object-related authorization and / or person-related authorization, and wherein the projection hologram and the image generator are configured for generating the display of the image, in particular during the generation of the projectable image by the image generator.

[0143] An image generator for producing at least one projectable image is a component that preferably generates the image information contained in the displayed image itself. The image information can be guided to the projection hologram in the form of light beams, where the displayed image is then preferably generated as a real and / or virtual image visible from the display area. The image generator can, for example, comprise a picture generating unit (PGU) and / or a (video) projector and include a projection and / or image template, at least one light source for illuminating the template, and / or at least one beam-shaping component, e.g., a lens. It can also be a laser projector, which preferably does not require an image template but generates the image by selectively controlling at least one laser beam.

[0144] The image sensor generates the image information displayed by the projection hologram, particularly upon input of an image sensor signal. An image sensor signal can, in particular, comprise an electromagnetic signal. The image sensor signal can preferably include the image information to be generated, which is then generated by the image sensor.

[0145] The at least one projection hologram encompassed by the transparent base body for the first display is in particular a diffuser surface onto which the image information is preferably projected or transferred analogously to a "classic" screen, so that a real and / or virtual image can be viewed from the display area.

[0146] The control unit is configured to output the image sensor signal to the image sensor during object-based and / or person-based authorization. A display appropriate to the respective authorization can be shown.

[0147] The projection hologram and the image generator are configured for generating the image display, particularly during the generation of the projectable image by the image generator. This preferably means that the light rays emitted by the image generator also reach at least part of the projection hologram. Furthermore, this means that the image generator and the projection hologram are matched with respect to the angular spectrum of the light rays incident on the projection hologram, the center-of-mass angle of the light rays incident on the projection hologram, the frequency spectrum of the light rays incident on the projection hologram, and / or the coherence of the light rays incident on the projection hologram. In this way, the image information generated by the image generator can be displayed particularly advantageously by the projection hologram.

[0148] It may be preferred that the image includes dynamically displayed image content, e.g., for displaying a holographic control element and / or an animation.

[0149] In a further preferred embodiment of the invention, a second display hologram is encompassed by the transparent base body, which is configured to generate the display by illumination from ambient light. Thus, in addition to at least one display activated by a signal from the control device, a display generated solely by ambient light can be produced, which, for example, indicates the detection range.

[0150] In a second aspect, the invention relates to a system for a door opening control of a door or a flap with a functionalized disc, comprising a transparent base body with a front and a back for the functionalized disc, a first holographic display for a person-directed display of an image in a defined first display area opposite the front and / or the back of the transparent base body, a control device and a first communication means for sending and receiving signals.

[0151] The first communication means and control device are configured for object-based authorization control of an associated second communication means for sending and receiving signals, particularly when the second communication means is located within the transmission and reception range of the first communication means. The object-based authorization control is based on the position and / or movement of the second communication means in relation to a predetermined proximity area of ​​the first communication means, as well as on the properties of signals exchanged between the first and second communication means. The holographic display and control device are configured to generate the display of the image during object-based authorization of the second communication means, and the control device is further configured to output an unlocking signal for opening the door upon at least one object-based authorization.

[0152] According to this aspect of the invention, in addition to unlocking the door, authorization can advantageously generate an image display, e.g., to show the position of the control component and / or to display a holographic control component. Other important information, such as the battery charge status, fuel level, or traffic information (e.g., for the commute to work) in a vehicle, can also be displayed. This improves usability, increases safety, and enhances efficiency in the respective application.

[0153] The fact that the holographic display is included in the system preferably means that suitable means for generating a holographic display are included in the system. These suitable means are sufficiently described in this document.

[0154] The fact that the holographic display and the control device are set up to generate the display of the image during the object-related authorization of the second means of communication can also mean that a new display of an image is generated, e.g. a new image can be generated where a different image was displayed before the authorization.

[0155] Preferably, the holographic display is a display using visible light, particularly in a wavelength range between 420 nm and 750 nm.

[0156] Preferably, the holographic display (also according to the first aspect) produces a real and / or virtual, in particular a floating, image.

[0157] It is evident to those skilled in the art that the advantages, definitions, and embodiments of the device according to the first aspect of the invention also apply to the claimed device according to the second aspect. For example, the descriptions of the system, the functionalized disk, and the transparent base body above also apply to the claimed device according to the second aspect of the invention.

[0158] In a preferred embodiment of the invention, the system comprises a light source for illuminating at least one first display hologram encompassed by the transparent base body upon input of a display signal, wherein the control device is configured to output the display signal to the light source during object-related authorization, and wherein the display hologram and the light source are configured to generate the display of the image upon illumination, in particular of the display hologram, by the light source.

[0159] The fact that the display hologram is encompassed by the transparent base body preferably means that the display hologram is arranged on or within the base body. The display hologram and the transparent base body can, for example, form two separate components prior to their arrangement.

[0160] In a further preferred embodiment of the invention, the system comprises an image generator for producing a projectable image upon input of an image generator signal and at least one first projection hologram encompassed by the transparent base body, wherein the control device is configured to output the image generator signal to the image generator during object-related authorization of the second communication means, wherein the projection hologram and the image generator are configured for generating the display of the image, in particular during the generation of the projectable image by the image generator. The display can then, for example, show the position of the operating component or show the holographic operating component itself.

[0161] In both the embodiment with a light source and the embodiment with an image sensor, the respective hologram can be illuminated in various ways: free-beam illumination can be selected, directed directly onto the hologram from outside the base body; illumination can take place through the base body, which serves as a light guide by directing the illumination rays, for example, by total internal reflection; and edgelit illumination of the hologram through the light guide can take place. This preferably also applies to the embodiments of the holographic display according to the first aspect of the invention.

[0162] In a further preferred embodiment of the invention, the system further comprises at least one holographic camera for stereoscopic image acquisition of a defined detection area opposite the front and / or the rear of the transparent base body, wherein the holographic camera has at least one recording hologram encompassed by the base body for deflecting light rays from the detection area, wherein the camera and the control device are configured for person-specific authorization control of a person captured by the stereoscopic image acquisition, wherein the person-specific authorization control is based on at least one characteristic of the person that can be determined by the stereoscopic image acquisition, and wherein the control device is configured to output an unlocking signal for opening the door in the case of object-specific authorization and person-specific authorization.This allows for the implementation of two-factor authentication.

[0163] In a further preferred embodiment of the invention, the control device is configured to enable person-specific authorization control only after object-related authorization.

[0164] In a further preferred embodiment of the invention, a locking component is included which is configured for locking or unlocking the door, wherein the locking component is configured for unlocking the door upon output of the unlocking signal by the control device.

[0165] In a further preferred embodiment of the invention, an operating component is included which is designed for the operation of the door by the person.

[0166] In a further preferred embodiment of the invention, the operating component is configured to activate the operating component when the unlocking signal is output by the control device.

[0167] In a further preferred embodiment of the invention, the operating component comprises a proximity sensor based on ultrasound, an optical sensor, a wireless communication interface and / or radar.

[0168] In a further preferred embodiment of the invention, the operating component comprises at least one capacitive sensor. Capacitive sensors are known, for example, from touchscreens and function particularly simply and reliably.

[0169] In a further preferred embodiment of the invention, the operating component comprises a holographically based operating component.

[0170] In a further preferred embodiment of the invention, the system comprises at least a second holographic display for displaying an image directed towards a person, wherein the second holographic display is configured to generate the displayed image from ambient light of the transparent base body under a predetermined illumination.

[0171] In a further preferred embodiment of the invention, the system comprises at least a second display hologram encompassed by the transparent base body for displaying the image directed towards the person, which is configured to generate the display by illumination from an ambient light of the hologram.

[0172] In a further preferred embodiment of the invention according to the first aspect or the second aspect, the display comprises a display of an operating component and / or an operating prompt for the operating component and / or a display of a desired detection position for the person in the detection area. The desired detection position is preferably encompassed by the detection area.

[0173] In a further preferred embodiment of the invention according to the first aspect or the second aspect, the holographic camera comprises at least one image sensor, wherein the recording hologram, transparent base body and image sensor are arranged for at least partial light transmission between the recording hologram and the image sensor by means of light rays guided in the base body.

[0174] At least one image sensor can also be referred to as a detector and / or detector system, wherein a detector system may preferably comprise at least two image sensors.

[0175] The recording hologram can preferably deflect the light to be recorded from the detection area in such a way that it is guided through the base body to the image sensor. For example, the light can be coupled in via an outer surface of the base body belonging to a planar part and then guided by the recording hologram towards the image sensor, which is located, for example, on a short lateral outer surface of the base body that does not belong to the planar part. The light can be guided directly to the image sensor, i.e., in particular without further reflections. However, it is also possible for the light to be deflected into the base body by the recording hologram at such an angle that it is guided to the image sensor with at least one total internal reflection at an outer surface of the base body. In this way, the base body can advantageously function as a light guide.

[0176] In a further preferred embodiment of the invention according to the first aspect or the second aspect, the transparent base body further comprises at least one first output hologram, which is configured to output the guided light rays from the transparent base body in the direction of the image sensor. This allows for a high degree of flexibility in the arrangement of the image sensor.

[0177] In one embodiment, the system comprises a functionalized waveguide for a detector system, wherein the waveguide has a transparent base body with a front and a back, wherein the base body has a partially transparent input coupling area and an output coupling area spaced therefrom in a first direction (R1), wherein the input coupling area comprises a diffractive structure as a receiving hologram which deflects only a portion of the radiation coming from an object to be detected, in particular in the detection area, and striking the front, such that the deflected portion propagates as coupled-in radiation in the base body by reflections to the output coupling area and strikes the output coupling area, wherein the output coupling area deflects at least a portion of the coupled-in radiation striking it such that the deflected portion exits the base body via the front or back.to encounter the detector system. The output coupling area preferably comprises a diffractive structure for deflection, in particular an output coupling hologram. Preferably, the extent of the input coupling area in a second direction (R2) transverse to the first direction (R1) is larger than the extent of the output coupling area (5) in the second direction (R2).

[0178] In a further preferred embodiment of the invention according to the first aspect or the second aspect system, the holographic camera is configured for stereoscopic image acquisition of a monochrome image, a multicolor image, and / or an infrared image. Monochrome preferably means that a frequency spectrum commonly perceived as "monochrome," e.g., red, is used for image acquisition. A monochrome image can be realized with particularly simple and inexpensive components. A multicolor image can comprise a continuous spectrum in the visible range, but it can also be an image composed of several colors. For example, the RGB (red, green, blue), CMY (cyan, magenta, yellow), and / or CMYK (plus black) color spaces can be used for image acquisition. Suitable holograms, e.g., a hologram stack and / or multiplex holograms, can be used for this purpose.Such multi-colored image captures allow, for example, more image information to be realized and can advantageously achieve greater security in authorization control.

[0179] An infrared image is, in particular, an image produced by capturing near-infrared radiation. Near-infrared radiation is preferably radiation in a wavelength range between 750 nm and 3 µm (micrometers), especially between 780 nm and 1.4 µm. Near-infrared radiation is, in particular, invisible to a person being detected.

[0180] An infrared image can also preferably include thermal radiation, which is preferably in the range of 3 µm to 50 µm. An infrared image with thermal radiation has the particular advantage that no residual and / or ambient light is required for person-related authorization checks, since the infrared radiation is generated primarily by the thermal radiation of the person being scanned.

However, it is also possible for the light to be coupled into the base body at such an angle in the direction of the display hologram or projection hologram that it is guided to the display hologram or projection hologram by at least one total internal reflection at an outer surface of the base body. In this way, the base body can advantageously function as a light guide.The display hologram and / or the projection hologram preferably couples the light out towards the display area. Another possible arrangement of the image generator or the light source is opposite the front and / or rear of the base body. For coupling into the base body, so that the light is guided within it as described above, a suitable optical element, e.g., a diffractive element, in particular a coupling hologram, or, for example, a reflective element, in particular a mirror, arranged within the base body, can be included.

Figure 6 shows two different examples of a front door using the described system. Figure 7 shows an embodiment of a holographic camera in a side view. Figure 8 shows another embodiment of a holographic camera in a side view. Figure 9 shows another embodiment of a holographic camera in a side view.

[0234] Figure 1 shows a section of a vehicle 1 with a door 3,which includes a system for object-based authorization control as described. The functionalized disk 5 It has a corresponding transparent base body. Typically, the functionalized disc 5 formed by the transparent base body. If object-related authorization is detected, a holographic display is shown. 7 generated. In this case, it is a holographic control element that uses a holographically displayed hand to indicate where the authorized person should place their hand to open the door. 3 to place.

These can be displayed, for example, in the event of an unsuccessful object-based and / or person-based authorization check.

[0244] Figure 6 shows two different examples of how a front door can be designed. 18 with the described system. At least one holographic camera. 19 for a stereoscopic image recording (preferably at least two) is included in the functionalized disc 5 includes, as it were, a view from the outside through the door. 18 into the interior behind the door 18 made possible by the holographic camera 19 a camera signal 21 the control unit 23to, which in turn uses the image recordings to carry out the further steps of the authorization control and, for example, sends an unlock signal upon authorization. 25 (The signal path is represented by the dashed arrow) to the locking component 26 outputs.

The image sensor 29 is located on a lower short side surface of the base body 30 arranged where the light rays are directed by total internal reflection. It would of course also be possible that the image sensor 29 with appropriate training of the recording hologram 9 on the upper short side surface of the base body 30 would be arranged if a separate functionalized disc 5 (dotted line) encompasses, there must be a separation between this and the base body. 30 A difference in the refractive index is realized, which results in total reflection in the base body. 5 This is made possible, for example, by a layer, especially a film with the appropriate properties, which is placed between the pane of glass.5 and base body 30 It is located, or it could be realized. It is also possible that there is an air gap between them.

[0249] Figure 9 Figure 1 shows a side view of an embodiment of a holographic camera. Except for the coupling of the light rays to the image sensor, which is described below. 29 is the structure essentially with the one from Figure 8 and apart from the differences of Figure 8 to Figure 7 It is identical to this one, therefore only the differences will be discussed here. Also in the basic body 30 according to Figure 8 The light rays are subjected to total internal reflection within the base body. 30 guided. However, the image sensor 29 in the example shown on a back side 32 of the base body and the guided light rays are separated by an output hologram 34 decoupled from the base body 30 and onto the image sensor 29directed. The output hologram 34 It can exhibit imaging properties. The decoupling hologram 34 can be used in a similar way to the recording hologram 9 on the base body 5 The image sensor can be attached to or integrated into the base body. 30 be arranged. The output hologram 34 It can include a transmissive or reflective hologram. If a separate functionalized disk is used... 5 (drawn with dotted lines) encompasses the part of the base body. 30, on the recording hologram 34 and image sensor 29 are located below or above (if the image sensor is located at an upper end of the base body). 30 is arranged) at a lower or upper end of the disc 5 It must be arranged so that seeing through the pane is not possible. 5 especially the image sensor 29is not affected or is not visible.

[0250] In an analogous manner as above in the Figures 7, 8 and 9 The analogous functioning of a holographic display can be described 7 These figures can be used to describe it. Instead of the image sensor. 29 However, this would mean a light source or image generator would be present instead of the recording hologram. 9 would use a display or projection hologram, the detection range 31 This could, for example, correspond to the display area, the decoupling hologram. 34 Instead, it would be a coupling hologram, and the overall beam path would run in the opposite direction.
