[0053] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 6-Figure 8-1 ,as well as Figure 9-Figure 15The imaging device 3 according to the first embodiment of the present invention is described. In the following description, the imaging device 3 is used in an ultrasonic diagnostic apparatus 100 as an example, but the invention is not limited thereto.

[0054] like Figure 6 As shown, the imaging device 3 according to the first embodiment of the utility model includes a housing, a flat lens, a sensor and a control component.

[0055] Specifically, a display screen 33 is provided in the housing 31, a first opening 311 is formed on the housing 31, and the flat lens 2 is provided at the first opening 311. The light emitted by the display screen 33 is suitable for irradiating the flat lens 2, and after passing through the flat lens 2, a floating real image 4 is formed on a side of the flat lens 2 away from the display screen 33. The sensing element 34 is provided on the housing 31, and the control component 35 is provided in the housing 31, and the control component 35 is located on a side of the display screen 33 away from the flat lens 2, and the control component 35 communicates with the display screen 33 and the sensing element 34 respectively.

[0056] For example, in Figure 6 In the example, a first opening 311 is formed on the front surface of the shell 31, the flat lens 2 is arranged at the first opening 311, and the display screen 33 is arranged on the rear side of the flat lens 2, and forms a certain angle with the flat lens 2. The control component 35 is arranged on the rear side of the display screen 33, and the display screen 33 is responsible for outputting the picture. By setting the display screen 33 to communicate with the control component 35, the control component 35 can control the display interface of the display screen 33, and the display screen of the display screen 33 can be the same as the display screen of an external device such as the key display screen 11 of the main body 1. When the light emitted by the display screen 33 passes through the flat lens 2, the flat lens 2 can reconstruct the light field of the light source, and project the mirror image into the air to form a floating real image 4 that is consistent with the light source (i.e., the display screen 33). As a result, a floating real image 4 that is completely consistent with the screen of the display screen 33 can be seen on the side of the flat lens 2 away from the display screen 33, and it switches synchronously. That is, the imaging screen of the floating real image 4 is the same as the display screen of the key display screen 11 of the main body 1. The floating real image 4 is the interface for observation during use. When the doctor 50 uses the ultrasonic diagnostic apparatus 100, the main body 1 can be operated through the floating real image 4, which is simple to operate. It should be noted that the imaging principle of the flat lens 2 is described in detail in the following description.

[0057] In addition, by setting the sensing element 34, when the operator, such as the doctor 50, operates the interface of the floating real image 4, the sensing element 34 is used to capture the non-contact touch signal, that is, the doctor 50's operation instruction on the floating real image 4 can be detected, and the operation instruction is fed back to the control component 35, and then fed back to the control module of the main body 1 (not shown) through the control component 35, so as to realize the control of the main body 1. At the same time, after the main body 1 receives the instruction and makes the corresponding operation, the corresponding operation signal can be fed back to the control component 35 to control the change of the display screen 33 and the floating real image 4. For example, by non-contact operation of the floating real image 4, the switching of different detection interface views of the ultrasonic diagnostic instrument 100 can be realized. The detection result image zooming, detection result image freezing, sampling frame size selection and change functions, detection result image measurement functions, etc. can be realized on the main body 1.

[0058] With such arrangement, a floating real image 4 having the same image as the display screen 33 can be formed on the imaging device 3, and the operator can switch the display image of the display screen 33 by operating the floating real image 4, so as to realize the control of the device connected to the imaging device 3. For example, when the imaging device 3 is connected to the main body 1 of the ultrasonic diagnostic apparatus 100, the image displayed by the floating real image 4 is the image of the key display screen 11 on the main body 1, so as to facilitate the contactless control of the main body 1. Of course, the imaging device 3 can also be set on other devices to realize the contactless control of the above-mentioned other devices. In addition, the imaging device 3 has a simple structure, low production difficulty and high production efficiency.

[0059] When the imaging device 3 is used for an ultrasonic diagnostic instrument, in the use scenario, after cleaning the hands, the probe, and the part to be tested, the medical staff holds the probe in one hand for testing, and the other hand only needs to touch the button on the floating real image 4. After the sensor 34 detects the touch signal, it transmits the signal to the control component 35. The control component 35 converts the touch signal into a key signal, and then sends the key signal to the main body 1. The control module of the main body 1 implements the corresponding function according to the received key signal. The doctor 50 can operate the patient 40 while operating the equipment according to his own subjective will, which improves the process of needing another doctor to cooperate and convey the will, and improves the efficiency of the operation. Moreover, there is no need to touch the physical buttons of the main body 1 to operate the main body 1, and no physical contact is required. The ultrasonic diagnostic instrument 100 device can be controlled by operating in the air, which can keep both hands of the doctor 50 in a pollution-free environment, greatly reducing the risk of cross-contamination, and making the entire diagnostic process cleaner and safer.

[0060] According to the imaging device 3 of the embodiment of the utility model, the imaging device 3 has a simple structure, low production difficulty and high production efficiency. In addition, by setting the sensing member 34 to communicate with the control component 35, after the operator operates the floating real image 4, the sensing member 34 can transmit the sensed operation signal to the control component 35, so that the control component 35 correspondingly controls the screen switching of the display screen 33, thereby realizing the contact between the operator and the floating real image 4 to control the display screen 33. The imaging device 3 is rich in functions and the user's experience is good. When the imaging device 3 is used for the ultrasonic diagnostic instrument 100, by setting the imaging device 3 and the main body 1 to communicate and dock, the two are used in combination with each other, and the doctor 50 can operate the main body 1 through the floating real image 4, which is simple to operate. The doctor 50 can operate the equipment according to his own subjective will while performing surgery on the patient 40, which improves the need for another doctor to cooperate and the process of conveying the will, and improves the efficiency of the operation. Moreover, there is no need to touch the physical buttons of the main body 1 to operate the main body 1. No physical contact is required. The ultrasonic diagnostic device 100 can be controlled by operating in the air, which can keep both hands of the doctor 50 in a pollution-free environment, greatly reducing the risk of cross-contamination and making the entire diagnostic process cleaner and safer.

[0061] According to some embodiments of the present invention, referring to Figure 6 The housing 31 includes a housing body 312 and a back plate 313. The housing body 312 is formed with the first opening 311, and a second opening 3121 is formed on a side of the housing body 312 away from the flat lens 2. The display screen 33 is disposed at the second opening 3121. The display screen 33, the housing body 312 and the flat lens 2 define a closed space 314 together.

[0062] For example, in Figure 6 In the example, the first opening 311 and the second opening 3121 are opposite to each other along the front-to-back direction of the shell 31, and there is a certain angle between the plane where the first opening 311 is located and the plane where the second opening 3121 is located. Thus, the display screen 33, the shell body 312 and the flat lens 2 jointly define a closed space 314, and the light emitted by the display screen 33 can be irradiated to the flat lens 2 through the closed space 314, reducing the scattering and loss of light, which is beneficial to the collection of light at the flat lens 2, and then beneficial to the imaging at the floating real image 4, improving the imaging quality, and being more beneficial to the observation and use of the user. For example, the shapes of the first opening 311 and the second opening 3121 are respectively rectangular, thereby facilitating the assembly of the shell body 312 with the display screen 33 and the flat lens 2, and improving the assembly efficiency. Moreover, the structure of the shell body 312 can also be simplified, which is beneficial to the production and processing of the shell body 312.

[0063] Combination Figure 6-Figure 8-1The back plate 313 is connected to the shell body 312, and the back plate 313 is arranged on the side of the display screen 33 away from the flat lens 2, and the control component 35 is located between the back plate 313 and the display screen 33. Figure 6 In the example, the back plate 313 is located at the rear side of the shell body 312, the control component 35 is arranged between the back plate 313 and the display screen 33, and the back plate 313 is also roughly arranged in a rectangular shape. In this way, when the back plate 313 is connected to the shell body 312, the back plate 313 can improve the overall structural strength of the shell 31, so as to facilitate the long-term use of the imaging device 3. In addition, the back plate 313 can cover the control component 35 to avoid exposing the control component 35 to the outside of the shell 31, which is conducive to the long-term use of the control component 35, prolonging the service life of the control component 35, and further prolonging the service life of the imaging component and the ultrasonic diagnostic instrument 100. In addition, the layout of the back plate 313, the display screen 33 and the control component 35 is reasonably arranged, which can reduce the space occupied by the control component 35 in the confined space 314, thereby avoiding the control component 35 blocking the propagation of light, so as to facilitate the imaging of the floating real image 4.

[0064] According to some embodiments of the present invention, Figure 6 One side of the display screen 33 and one side of the flat lens 2 are close to each other, and the other side of the display screen 33 and the other side of the flat lens 2 are away from each other and extend toward the bottom of the shell body 312.

[0065] For example, in Figure 6 In the example, the upper side of the display screen 33 and the upper side of the flat lens 2 are close to each other, the lower side of the display screen 33 and the lower side of the flat lens 2 are far away from each other, the lower side of the display screen 33 is connected to the bottom of the shell body 312, the lower side of the flat lens 2 is connected to the bottom of the shell body 312, and the cross-sectional shape of the enclosed space 314 along the front-to-back direction is roughly triangular. In this way, the positions of the display screen 33 and the flat lens 2 are reasonably set, so that the plane where the floating real image 4 is located is suitable for user observation, which facilitates the use of the imaging device 3.

[0066] According to some optional embodiments of the present invention, combined with Figure 6 , the cross-sectional shape of the shell body 312 is a triangle. In this arrangement, the display screen 33 and the flat lens 2 can be respectively located on the two sides of the above triangle, so that the display screen 33, the flat lens 2 and the shell body 312 can jointly define a closed space 314. In addition, the structure of the shell body 312 is simplified, which is conducive to the production and processing of the shell body 312, and the production cost is low. In addition, the structural stability of the shell body 312 is high, and the imaging device 3 can be placed on a table, which is conducive to the long-term stable use of the imaging device 3.

[0067] According to some embodiments of the present invention, Figure 6The control component 35 includes a mainboard 351 and a communication module 352. The mainboard 351 is arranged on the back plate 313, and the mainboard 351 communicates with the display screen 33 and the sensor 34 respectively. The communication module 352 is arranged on one side of the back plate 313 adjacent to the bottom of the shell body 312, and the communication module 352 communicates with the mainboard 351. The mainboard 351 can communicate with the control module of the main body 1 through the communication module 352. For example, in Figure 6 In the example of , the mainboard 351 can be an industrial computer, which is responsible for processing the display of the floating real image 4 and the non-contact touch signal processing. The mainboard 351 can receive the signal feedback of the sensor 34 and control the display interface of the display screen 33. In addition, the communication module is used to send the operation instructions of the mainboard 351 to realize the control of the main body 1. At the same time, the communication module 352 can also feedback the operation of the main body 1 to the mainboard 351, so as to control the display of the display screen 33 through the mainboard 351. In addition, by setting the communication module 352 on one side adjacent to the bottom of the shell body 312, it is convenient to transmit signals between the communication module 352 and the control module of the main body 1.

[0068] According to some embodiments of the present invention, Figure 6 The main board 351 has a plurality of first interfaces 3511, and the imaging device 3 further includes a plurality of transmission lines 36, one end of each of the plurality of transmission lines 36 is connected to the plurality of first interfaces 3511, and the other end of each of the plurality of transmission lines 36 is connected to the display screen 33, the sensor 34, the communication module 352, and the external power supply. In the description of the present utility model, "plurality" means two or more.

[0069] For example, in Figure 6In the example, four first interfaces 3511 are provided on the mainboard 351, and the imaging device 3 includes four transmission lines 36, which are connected to the four first interfaces 3511 one by one, and the other ends of the four transmission lines 36 are respectively electrically connected to the interface of the display screen 33, the sensor 34, the communication module 352 and the external power supply. For example, the four first interfaces 3511 are respectively a serial port, a power interface, an HDMI interface and a USB interface. The serial port is connected to the corresponding transmission line 36 for connecting the mainboard 351 and the communication module 352, and the power interface is connected to the corresponding transmission line 36 for connecting the power line 7 of the mainboard 351. The power line 7 is used to connect to the external power supply. The power line 7 has a 220V AC to 12V DC conversion function to power the ultrasonic diagnostic instrument 100. The HDMI interface is connected to the corresponding transmission line 36 for connecting the mainboard 351 and the display screen 33, and the USB interface is connected to the corresponding transmission line 36 for connecting the sensor 34 and the mainboard 351. In addition, by providing a plurality of first interfaces 3511 and a plurality of transmission lines 36, the display screen 33, the sensor 34, the communication module 352 and the external power supply are electrically connected to the mainboard 351, and the connection operation is simple, which is conducive to the rapid assembly of the imaging device 3. It should be noted that the number of the first interfaces 3511 and the transmission lines 36 can be set according to the specific use to better meet the actual application.

[0070] Optionally, a third interface 3131 is provided on the back panel 313, and the third interface 3131 is provided near the communication module 352, and the power line 7 is connected to the corresponding transmission line 36 through the third interface 3131. Thus, the imaging device 3 can be connected to an external power source through the power line 7. For example, the power line 7 can be inserted at the third interface 3131, which is convenient for plugging and unplugging the power line 7 and is more convenient to use.

[0071] According to some embodiments of the present invention, Figure 6 A second interface 315 is provided on the shell, and the second interface 315 is electrically connected to the communication module 352. The imaging device 3 further includes a connecting line 5, one end of which is detachably connected to the second interface 315, and the other end of the connecting line 315 extends to the outside of the shell body 312.

[0072] For example, in Figure 1 and Figure 6In the example, the second interface 315 is located at the bottom of the back panel 313, the one end of the connecting line 5 communicates with the control component 35 through the second interface 315, and the other end of the connecting line 5 extends to the outside of the shell body 312 to be plugged into the main body 1 to be electrically connected to the control module of the main body 1. Of course, when the imaging device 3 is used for other equipment, the other end of the connecting line 315 can be connected to the other equipment to achieve communication with the other equipment. With this arrangement, the second interface 315 facilitates the connection between the connecting line 5 and the imaging device 3, and is conducive to the plugging and unplugging of the one end and the other end of the connecting line 5, thereby facilitating the connection between the imaging device 3 and the main body 1. In addition, it is also convenient for the replacement and maintenance of the connecting line 5.

[0073] When the ultrasonic diagnostic apparatus 100 is needed, the imaging device 3 can communicate with the main body 1 through the connecting line 5, so that the screen of the key display screen 11 on the main body 1 is synchronized to the display screen 33 of the imaging device 3 and then presented on the floating real image 4, so as to control and operate the main body 1 through the contactless touch of floating imaging. The above-mentioned imaging device 3 and the main body 1 are two independent instruments. When in use, the control module and the control component 35 are communicated through the connecting line 5, so that the main body 1 and the imaging device 3 can cooperate with each other and work together. After the ultrasonic diagnostic apparatus 100 is used, the main body 1 and the imaging device 3 can be placed separately. For example, the connecting line 5 is a USB connecting line 5, which should be inserted into the second interface 315 on the shell 31, such as a USB interface, and the USB interface on the main body 1 when in use, so as to provide data exchange between the imaging device 3 and the main body 1.

[0074] In addition, the control component 35 of the imaging device 3 and the control module of the main body 1 are communicated through the connecting line 5. The imaging device 3 is fixed on or near the original ultrasound device in a proper position by means of a physical structure. The connection and cooperation are realized by opening the communication protocol between the imaging device 3 and the main body 1, so that the physical button operation forms such as buttons, trackballs, knobs, and dials on the main body 1 are converted into interactive aerial imaging operations (such as Figure 8-3 As shown). Clicking on the imaging device 3 can obtain the same operating effect as the original physical button or knob. Since the imaging device 3 adopts the design of air imaging and air interaction, operating on the imaging device 3 can satisfy the functions that can be achieved by the original operation mode, and can prevent bacteria and virus contamination caused by contact. In terms of electrical structure, the imaging device 3 is connected to the main body 1 only through a small number of communication lines such as the connecting line 5, and is equipped with an independent power supply interface, which is simple to connect and reduces the trouble of wiring. In terms of software use, the display of floating imaging is as close to the high-frequency usage scenarios of operators as possible, and the function keys and knobs that need to be frequently used in the original ultrasonic diagnostic equipment are extracted, so that most of the operations in normal use can be performed on the imaging device 3. You can also add other buttons as needed for easy use.

[0075] According to some embodiments of the present invention, Figure 6 , protective members 3321 are respectively provided on both sides of the thickness direction of the flat plate 2. Figure 6 In the example, the side surface of the protective member 3321 located on the front side of the flat lens 2 facing the flat lens 2 is bonded to the side surface of the flat lens 2 away from the display screen 33, and the side surface of the protective member 3321 located on the rear side of the flat lens 2 facing the flat lens 2 is bonded to the side surface of the raw material floating real image 4 of the flat lens 2. In this way, the protective member 3321 can protect the flat lens 2, thereby preventing the flat lens 2 from being damaged, thereby extending the service life of the flat lens 2. In addition, the flat lens 2 is bonded to the protective member 3321, which can avoid bubbles between the protective member 3321 and the flat lens 2, thereby avoiding affecting the propagation of light passing through the flat lens 2 and the protective member 3321, improving the imaging effect of the floating real image 4 of the imaging device 3, and thus helping to further improve the user's visual sense. In addition, the protective member 3321 can also modify the imaging device 3, thereby improving the aesthetics of the imaging device 3. For example, the protective member 3321 can be tempered glass, which can protect the flat lens 2 without affecting the imaging of the floating real image 4.

[0076] According to some optional embodiments of the present invention, the sensing element 34 is an interactive sensor, which is located above the first opening 311, and the interactive sensor and the floating real image 4 are on the same plane. Figure 6 In the example, the interactive sensor is located at the upper end of the housing 31, and the light emitted by the interactive sensor, such as infrared light, is parallel to and coincides with the plane where the floating real image 4 is located.

[0077] The general process of switching the operation interface of the floating real image 4 is as follows: first, the interface displayed on the display screen 33 is controlled by the main board 351, and then the interface displayed on the display screen 33 forms a floating real image 4 with the same display screen through the flat lens 2. When the user contacts the floating real image 4, the interactive sensor transmits the received induction to the main board 351 in the form of information, and the main board 351 transmits the signal to the control module of the main body 1. Then the main board 351 controls the interface displayed on the display screen 33 according to the information received from the main body 1 to realize the switching of the floating real image 4 screen. Therefore, the user can complete the operation and control of the display screen 33 by touching the button icon displayed on the floating real image 4, thereby making the operation of the imaging device 3 simpler and more convenient, and reducing the difficulty of use. In addition, in the process of switching the interface of the display screen 33, by combining the interactive sensor, the user can directly interact with the floating real image 4 without touching the display screen 33 itself, achieving the purpose of contactless control, thereby avoiding the risk of cross infection during use, thereby improving the hygiene and safety of use, and solving a difficult problem in medicine.

[0078] According to some embodiments of the present invention, Figure 6 , at least one support member 37 is provided at the bottom of the housing 31. Figure 8-1 In the example, two supporting members 37 are provided at the bottom of the housing 31. When the imaging device 3 is provided outside the main body 1, the main body 1 is an ultrasonic diagnostic device, and the control platform (such as buttons) of the ultrasonic diagnostic device is not processed in any way. The imaging device 3 is fixed to an appropriate position on or near the ultrasonic diagnostic device through a physical structural member, and the communication protocol between the imaging device 3 and the main body 1 is established to achieve connection and collaboration. For example, Figure 3 and Figure 4 As shown, the imaging device 3 can be placed on the mobile cart 10 or the table 20. Therefore, the support member 37 can be used to support the housing 31, so that the imaging device 3 can be stably placed at the position where the imaging device 3 needs to be placed, so as to facilitate the formation of the floating imaging screen at an angle that is convenient for the user to watch, so as to be more convenient for the use of the ultrasonic diagnostic apparatus 100. It should be noted that the support member 37 can be set in various forms, for example, Figure 3 In the example of , one end of the support member 37 is connected to the housing 31, and the other end of the support member 37 can be flipped relative to the above end of the support member 37 and the bottom surface of the housing 31 to support the housing 31, and at the same time, the housing 31 can be lifted to a certain height to facilitate the use of the imaging device 3. Or, as Figure 6 As shown, one end of the support member 37 is connected to the shell 31, and the other end of the support member 37 can rotate around the above-mentioned one end of the support member 37 within the plane where the bottom surface of the shell 31 is located, so as to improve the stability of the shell 31 placed on the surface of the mobile cart 10 or the table 20, thereby improving the stability of the imaging device 3 in use.

[0079] Reference below Figure 9-Figure 15 The structure and imaging principle of the flat lens 22 in the present invention are described as follows.

[0080] According to some embodiments of the present utility model, the flat lens 2 includes two transparent substrates 23 and two optical waveguide unit arrays, the two optical waveguide unit arrays include a first optical waveguide array 21 and a second optical waveguide array 22, each transparent substrate 23 has two optical surfaces, the two optical waveguide unit arrays are arranged between the two transparent substrates 23, and the optical waveguide extension directions of the two optical waveguide unit arrays are arranged orthogonally.

[0081] like Figure 9-10As shown, the flat lens 2 includes two transparent substrates 23, and a first optical waveguide array 21 and a second optical waveguide array 22 disposed between the two transparent substrates. The first optical waveguide array 21 and the second optical waveguide array 22 are closely attached to each other and orthogonally arranged on the same plane. Preferably, the first optical waveguide array 21 and the second optical waveguide array 22 have the same thickness, which is convenient for design and production. Specifically, as shown in FIG. Fig. 9 As shown, the flat lens 2 includes a first transparent substrate, a first optical waveguide array 21, a second optical waveguide array 22 and a second transparent substrate in sequence from the display screen 33 side to the floating real image 4 side.

[0082] The first transparent substrate and the second transparent substrate each have two optical surfaces, and the transparent substrate 23 has a transmittance of 90%-100% for light with a wavelength between 390nm and 760nm. The material of the transparent substrate 23 can be at least one of glass, plastic, polymer and acrylic resin, and is used to protect the optical waveguide array and filter out excess light. It should be noted that if the strength of the first optical waveguide array 21 and the second optical waveguide array 22 after being closely orthogonally bonded is sufficient, or the installation environment has thickness restrictions, then only one transparent substrate 23 may be configured or no transparent substrate 23 may be configured at all.

[0083] like Fig.10 As shown, the first optical waveguide array 21 and the second optical waveguide array 22 are composed of a plurality of reflective units 24 with rectangular cross sections, and the lengths of the reflective units 24 are limited by the outer dimensions of the optical waveguide array and thus vary in length. The extending direction of the reflective units 24 in the first optical waveguide array 21 is X, the extending direction of the reflective units 24 in the second optical waveguide array 22 is Y, and the Z direction is the thickness direction of the optical waveguide array. The extending directions (optical waveguide array directions) of the reflective units 24 in the first optical waveguide array 21 and the second optical waveguide array 22 are perpendicular to each other, that is, from the Z direction (thickness direction), the first optical waveguide array 21 and the second optical waveguide array 22 are orthogonally arranged, so that the two light beams in the orthogonal directions converge at one point, and ensure that the object image plane (light source side and imaging side) is symmetrical relative to the flat lens 2, resulting in an equivalent negative refraction phenomenon, and realizing aerial imaging.

[0084] like Fig.11As shown, the first optical waveguide array 21 or the second optical waveguide array 22 is composed of a plurality of parallelly arranged reflective units 24 arranged obliquely at 45° from the user's viewing angle. Specifically, the first optical waveguide array 21 may be composed of reflective units 24 arranged side by side at 45° in the lower left direction and having a rectangular cross section, and the second optical waveguide array 22 may be composed of reflective units 24 arranged side by side at 45° in the lower right direction and having a rectangular cross section. The arrangement directions of the reflective units 24 in the two groups of optical waveguide arrays can be interchanged. For example, the extending direction of the reflective units 24 in the first optical waveguide array 21 is Y, the extending direction of the reflective units 24 in the second optical waveguide array 22 is X, and the Z direction is the thickness direction of the optical waveguide array. From the Z direction (thickness direction), the first optical waveguide array 21 and the second optical waveguide array 22 are arranged orthogonally, so that the two light beams in the orthogonal directions converge at one point, and ensure that the object image plane (light source side and imaging side) is symmetrical relative to the flat lens 2, resulting in an equivalent negative refraction phenomenon, and realizing aerial imaging. The optical waveguide material has an optical refractive index n1. In some embodiments, n1>1.4, for example, n1 is 1.5, 1.8, 2.0, etc.

[0085] like Fig.14 As shown, for the first optical waveguide array 21 and the second optical waveguide array 22, there are two intersection surfaces between each reflective unit 24 and its adjacent reflective unit 24, and each intersection surface is connected by an adhesive 26 with good light transmittance. Preferably, the adhesive 26 can be selected from a photosensitive adhesive or a thermosetting adhesive, and the thickness of the adhesive 26 is T1, and satisfies T1>0.001mm, for example, T1=0.002mm or T1=0.003mm or T1=0.0015mm, and the specific thickness can be set according to specific needs. Adhesive 26 is provided between adjacent optical waveguide arrays in the flat lens 2 and between the optical waveguide array and the transparent substrate 23 to increase firmness.

[0086] In some embodiments, the cross section of the reflective unit 24 may be rectangular, and a reflective film 25 may be provided on one or both sides of the arrangement direction of the reflective unit 24. Specifically, in the arrangement direction of the optical waveguide array, both sides of each reflective unit 24 are plated with a reflective film 25, and the material of the reflective film 25 may be a metal material such as aluminum, silver, or other non-metallic compound material that realizes total reflection. The function of the reflective film 25 is to prevent light from entering the adjacent optical waveguide array due to lack of total reflection to form stray light and affect imaging. Alternatively, each reflective unit 24 may also add a dielectric film on the reflective film 25, and the function of the dielectric film is to improve the light reflectivity.

[0087] The cross-sectional width a and cross-sectional length b of a single reflective unit 24 satisfy 0.1mm≤a≤5mm, 0.1mm≤b≤5mm. Further, in order to obtain a better imaging effect, 0.1mm≤a≤2mm, 0.1mm≤b≤2mm are satisfied. For example, a=0.2mm, b=0.2mm; or, a=0.5mm, b=0.5mm. When displaying on a large screen, the large size requirement can be achieved by splicing multiple optical waveguide arrays. The overall shape of the optical waveguide array is set according to the needs of the application scenario. In this embodiment, the two groups of optical waveguide arrays are rectangular in structure as a whole, the two diagonal reflective units 24 are triangular, and the middle reflective unit 24 is a trapezoidal structure. The lengths of the single reflective units 24 are not equal. The reflective units 24 located on the diagonal of the rectangle are the longest, and the reflective units 24 at both ends are the shortest. In addition, the flat lens 2 can also include an anti-reflection component and a viewing angle control component. The anti-reflection component can improve the overall transmittance of the flat lens and improve the clarity and brightness of the floating real image 4. The viewing angle control component can be used to eliminate the residual image of the floating real image 4, reduce the dizziness of the observer, and prevent the observer from peeping into the inside of the device from other angles, thereby improving the overall aesthetics of the device. The anti-reflection component and the viewing angle control component can be combined, or they can be independently arranged between the transparent substrate 23 and the waveguide array, between two layers of waveguide arrays, or on the outer layer of the transparent substrate 23.

[0088] Specifically, the aerial imaging principle of the floating real image of the utility model is as follows:

[0089] At the micrometer scale, a mutually orthogonal double-layer waveguide array structure is used to perform orthogonal decomposition of any optical signal. The original signal is projected onto the first optical waveguide array 21, and a rectangular coordinate system is established with the original signal projection point as the origin and perpendicular to the first optical waveguide array 21 as the x-axis. In the rectangular coordinate system, the original signal is decomposed into two mutually orthogonal signals, signal X located on the x-axis and signal Y located on the y-axis. Among them, when signal X passes through the first optical waveguide array 21, it is totally reflected on the surface of the reflective film 25 at the same reflection angle as the incident angle; at this time, signal Y remains parallel to the first optical waveguide array 21, and after passing through the first optical waveguide array 21, it is totally reflected on the surface of the reflective film 25 at the same reflection angle as the incident angle on the surface of the second optical waveguide array 22. The reflected optical signal composed of the reflected signal Y and the signal X is mirror-symmetrical with the original optical signal. Therefore, light rays from any direction can achieve mirror symmetry when passing through the flat lens 2. Divergent light rays from any light source will converge into a floating real image 4 at a symmetrical position when passing through the flat lens 2. The imaging distance of the floating real image 4 is the same as the distance from the flat lens 2 to the image source, i.e., the display screen 33, which is an equidistant imaging. Moreover, the floating real image 4 is located in the air and does not require a specific carrier, but directly presents a real image in the air. Therefore, the image in the space seen by the user is the image emitted by the display screen 33.

[0090] In the embodiment of the utility model, when the light emitted by the light source of the display screen 33 passes through the flat lens 2, the above process occurs on the flat lens 2. Specifically, Fig.14 As shown, the incident angles of the light on the first optical waveguide array 21 are α1, α2 and α3 respectively, and the reflection angles of the light on the first optical waveguide array 21 are β1, β2 and β3, wherein α1=β1, α2=β2, α3=β3. After being reflected by the first optical waveguide array 21, the incident angles of the light on the second optical waveguide array 22 are γ1, γ2 and γ3 respectively, and the reflection angles of the light on the second optical waveguide array 22 are δ1, δ2 and δ3 respectively, wherein γ1=δ1, γ2=δ2, γ3=δ3.

[0091] Furthermore, the incident angles after convergence imaging are α1, α2, α3…α n , the distance between the light source of the display screen 33 and the flat lens 2 is L, then the distance between the imaging position of the floating real image and the flat lens is also L, and the visible angle ε of the floating real image 4 is 2 times max(α).

[0092] It is understandable that if the size of the optical waveguide array is small, the image can only be seen at a certain distance from the imaging side of the optical waveguide array; and if the size of the optical waveguide array becomes larger, a larger imaging distance can be achieved, thereby increasing the field of view.

[0093] Preferably, the angle between the flat lens 2 and the display screen 33 is set to be within the range of 45°±5°, so that the size of the flat lens 2 can be effectively utilized, the imaging quality can be improved, and the residual image effect can be reduced. In addition, if there are other requirements for the imaging position, other angles can be selected at the expense of some imaging quality. Preferably, the size of the flat lens 2 is set to be able to display the floating real image 4 presented by the entire display screen 33. However, if only a part of the display screen 33 needs to be seen in actual use, the size and position of the flat lens 2 can also be freely adjusted according to the actual display screen, and there is no restriction on this.

[0094] In addition, the above mainly describes the imaging principle of the flat lens 2 using a double-layer optical waveguide array structure. In other embodiments, if the surrounding surfaces are all set as a plurality of cubic columnar reflective units 24 with a reflective film 25, and the plurality of cubic columnar reflective units 24 are arranged in an array along the X and Y directions in a layer of optical waveguide array structure, that is, two layers of optical waveguide arrays are merged into one layer, its imaging principle is the same as that of the double-layer optical waveguide array structure, and it can also be used as the structure of the flat lens 2.

[0095] In the embodiment, the first optical waveguide array 21 and the second optical waveguide array 22 have the same thickness, so that the complexity of the structure of the first optical waveguide array 21 and the second optical waveguide array 22 can be simplified, the difficulty of manufacturing the first optical waveguide array 21 and the second optical waveguide array 22 can be reduced, the production efficiency of the first optical waveguide array 21 and the second optical waveguide array 22 can be improved, and the production cost of the first optical waveguide array 21 and the second optical waveguide array 22 can be reduced. It should be noted that the same thickness here is a relative range, not absolutely the same, that is, for the purpose of improving production efficiency, there can be a certain thickness difference between the optical waveguide arrays without affecting the quality of aerial imaging.

[0096] According to some embodiments of the utility model, the imaging mode of the display screen 33 may include RGB (red, green, blue) light emitting diodes (Light Emitting Diode, LED), LCD (Liquid Crystal Display), LCOS (Liquid Crystal on Silicon) devices, OLED (Organic Light-Emitting Diode, organic light-emitting diode) arrays, projections, lasers, laser diodes or any other suitable displays or stereoscopic displays, without limitation.

[0097] According to the second aspect of the present invention, the ultrasonic diagnostic apparatus 100 is combined with Figure 1-Figure 8-3 , including an imaging device 3 and a control module, the imaging device 3 is the imaging device 3 according to the first aspect embodiment mentioned above, and the control module communicates with the control component 35 of the imaging device 3.

[0098] In this way, the control module can be used to control the operation of the main body 1, feed back the operation of the main body 1 to the imaging device 3, and can also receive instructions transmitted by the imaging device 3, so as to facilitate the use of the ultrasonic diagnostic apparatus 100. For example, when the imaging device 3 is arranged outside the main body 1, the main body 1 is a traditional ultrasonic diagnostic device, which is a third-party product and provides the doctor 50 with ultrasonic detection, diagnosis and other functions.

[0099] According to the ultrasonic diagnostic instrument 100 of the embodiment of the utility model, by adopting the above-mentioned imaging device 3, the imaging device 3 and the main body 1 communicate and connect to perform collaborative control, and the two are used in combination with each other, and the doctor 50 can operate the main body 1 through the floating real image 4, which is simple to operate. The doctor 50 can operate the equipment according to his own subjective will while performing surgery on the patient 40, which improves the process of needing another doctor to cooperate and convey the will, and improves the efficiency of the operation. Moreover, there is no need to touch the physical buttons of the main body 1 to operate the main body 1, and no physical contact is required. The ultrasonic diagnostic instrument 100 equipment can be controlled by operating in the air, which allows the doctor 50's hands to be in a pollution-free environment, greatly reducing the risk of cross-contamination, and making the entire diagnostic process cleaner and safer.

[0100] Optionally, combined Figure 1 , Figure 4-Figure 5 When the imaging device 3 is arranged outside the main body 1, the imaging device 3 mainly provides non-contact operation, so that medical staff can still use the ultrasonic diagnostic instrument 100 normally without any physical contact. In terms of physical structure, the imaging device 3 supports a variety of combinations and installation methods. It can be fixed to both sides of the main body 1 through detachable structural parts so that the device can move with the main body 1. It can also be carried by a mobile cart 10, and can even be embedded in the wall 30, embedded in a cart, placed on a desktop and other spaces. For example, Figure 1 , Figure 4-Figure 5 In the example, the main body 1 can be the original ultrasonic diagnostic equipment, and the original ultrasonic diagnostic equipment control platform does not perform any processing. The ultrasonic diagnostic equipment is a third-party product, which provides the doctor 50 with ultrasonic detection and diagnosis functions. The imaging device 3 can be placed in different positions to suit different occasions. When the imaging device 3 is embedded in the wall 30, embedded in the cart, or placed on the desktop, the imaging device 3 can be used by communicating with the main body 1 through the connecting line 5, which is convenient and quick to use. Moreover, the user can place the imaging device 3 in different positions according to needs, which improves the flexibility of using the imaging device 3.

[0101] In use, the doctor 50 can fix the imaging device 3 to any suitable position of the main body 1 according to the actual use situation. For example, when the position of the main body 1 is relatively fixed, and the space is small, and it is inconvenient to fix the imaging device 3 on both sides of the main body 1, the imaging device 3 and its connecting rod 6 can be removed, and only the necessary communication interface is retained, and the main body 1 is placed in other places with sufficient space or convenient for use. Alternatively, in a scenario where the ultrasonic diagnostic instrument 100 needs to be moved frequently, the imaging device 3 and its connecting rod 6 can be fixed to both sides of the main body 1 so that it can be moved together with the main body 1.

[0102] According to some embodiments of the present invention, Figure 1The ultrasonic diagnostic apparatus 100 further includes a main body 1 and a connecting rod 6. The control module is disposed on the main body 1. The connecting rod 6 is disposed between the main body 1 and the imaging device 3. The connecting rod 6 drives the imaging device 3 to move relative to the main body 1. For example, the connecting rod 6 drives the imaging device 3 to rotate and rise and fall relative to the main body 1. Figure 1 In the example, one end of the connecting rod 6 is connected to the main body 1, and the other end of the connecting rod 6 is connected to the housing 31, so that the imaging device 3 and the main body 1 are connected as a whole, so that the imaging device 3 can move with the movement of the main body 1. In addition, the connecting rod 6 is responsible for the connection between the imaging device 3 and the main body 1, and provides functions such as lifting, pitching, and rotating so that the operator can adjust the operating angle.

[0103] Optionally, a connection port 316 is provided at the bottom of the shell 31, and the other end of the connecting rod 6 is connected to the connection port 316. The connecting rod 6 includes a first connecting rod segment 61 and a second connecting rod segment 62 that are rotatably connected. One end of the first connecting rod segment 61 is rotatably connected to the main body 1, and the other end of the first connecting rod segment 61 is connected to one end of the second connecting rod segment 62. The other end of the second connecting rod segment 62 is rotatably connected to the shell 31, so that the shell 31 can be rotated, flipped and lifted relative to the main body 1, so that the operator can adjust the operating angle. Moreover. The connecting rod 6 has a simple structure, is easy to use, and is easy to produce and process. The connecting rod 6 can freely adjust the height angle, so that the operator can use it in the most comfortable position. If necessary, the connecting rod 6 can also be removed, and the imaging device 3 can be placed in any suitable space for use.

[0104] According to some optional embodiments of the present invention, combined with Figure 2 , the imaging device 3 is arranged in the main body 1, and the display screen 33 is a key display screen of the main body 1. For example, in Figure 2 In the example, the imaging device 3 is entirely arranged inside the main body 1, the flat lens 2 and the protective member 3321 are located at the position of the original key display screen 11 of the main body 1, and the display screen 33 is set as a display screen 33 built into the main body 1. Thus, the key display screen 11 and the display screen 33 of the imaging device 3 are integrated into one body. Compared with the above-mentioned imaging device 3 being located outside the main body 1, there is no need for the key display screen 11 and the display screen 33 of the imaging device 3 to communicate, and the display content of the display screen 33 can be directly controlled by the control module to form a floating real image 4 on the front side of the protective member 3321. For example, the display screen of the floating real image 4 is shown in Figure 8-3.

[0105] Other structures and operations of the ultrasonic diagnostic apparatus 100 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
