Description

Technical Field

[0001] This application relates to the field of telescopes, and more particularly to an augmented reality telescope. Background Technology

[0002] Currently, telescopes, as important optical instruments, play a crucial role in numerous fields such as astronomical observation, military reconnaissance, and outdoor exploration. With continuous technological advancements, the performance and functionality of telescopes are constantly improving, evolving from simple optical structures to complex systems integrating multiple advanced technologies. This provides people with more powerful tools for exploring the unknown world and greatly expands humanity's field of vision.

[0003] In related technologies, various methods are typically employed to achieve different imaging effects to meet diverse observational needs. For example, some astronomical telescopes incorporate structures such as objective lenses, eyepieces, finder scopes, reflecting mirrors, angle mirrors, and shifting components. Objective lenses collect light and form an initial image, while eyepieces magnify the image for observation. Finder scopes help observers quickly locate target celestial objects, and components like plane mirrors alter the direction of the light path. Shifting components allow for the movement of certain parts to adjust the observational effect. Other telescopes achieve different magnifications and image qualities through different combinations of optical lenses and adjustments to their positions.

[0004] Regarding the aforementioned technologies: Although this solution achieves the switching of optical paths, its function is still relatively simple in nature. It only solves the problem of switching between the two traditional optical functions of "main observation" and "auxiliary star finding", and fails to provide truly diversified imaging modes, making it difficult to meet the diverse observation needs of users. Summary of the Invention

[0005] To meet the diverse observation needs of users, this application provides an augmented reality telescope.

[0006] This application provides an augmented reality telescope, which employs the following technical solution: An augmented reality telescope includes: The main body, wherein a dichroic mirror is disposed within the main body; An objective lens module is disposed within the main body along the first optical axis. The objective lens module is used to receive celestial rays containing visible light and infrared light. An eyepiece module is disposed within the main body along a second optical axis, the second optical axis intersecting the first optical axis; An image projection module includes an image receiving component and a projection component respectively disposed within the main body, wherein the image receiving component is disposed along the first optical axis and the projection component is disposed along the second optical axis; The dichroic mirror is located between the objective lens module, the eyepiece module, the image receiving component, and the projection component, and the dichroic mirror has a first position and a second position; When the dichroic mirror is in the first position, it intersects both the second optical axis and the first optical axis. At this time, the dichroic mirror is configured as follows: a) Reflecting visible light from the celestial rays to the eyepiece module; b) Transmitting infrared light from the celestial rays to the image receiving component; and c) The visible light image transmitted from the projection component, together with the reflected visible light, enters the eyepiece module to achieve superimposed imaging; When the dichroic mirror is in the second position, it does not intersect with the first optical axis, allowing the celestial light to propagate unobstructed along the first optical axis to the image receiving component.

[0007] By employing the above technical solution, when the dichroic mirror is in the first position, it reflects visible light from celestial objects to the eyepiece module, transmits infrared light to the image receiving component, and simultaneously transmits a visible light image from the projection component, which is superimposed with the reflected visible light to form an image. This achieves fused observation of optical scenes and digital information, meeting the requirements of mixed reality imaging. When the dichroic mirror is in the second position, celestial light can propagate unobstructed along the first optical axis to the image receiving component, achieving photographic imaging. Therefore, this telescope solves the problem that traditional telescopes cannot simultaneously meet the requirements of mixed reality imaging and photographic imaging, expanding its application scenarios and functions, and satisfying the diverse observation needs of users.

[0008] Optionally, the image projection module includes a processor disposed within the main body. The processor is electrically connected to both the image receiving component and the projection component. The processor is used to process the image information acquired by the image receiving component and control the projection component to project.

[0009] By adopting the above technical solution, the processor is electrically connected to both the image receiving component and the projection component. It can process the celestial light image information acquired by the image receiving component, such as identifying constellations and stars, or generating augmented reality information by combining internally stored star map data. Simultaneously, the processor can control the projection component to project the processed image information. A dichroic mirror, located between the projection component and the eyepiece module, and between the image receiving component and the objective lens module, reflects and transmits light, adjusting the light propagation path so that the image projected by the projection component accurately reaches the eyepiece module. This allows the user to observe the corresponding image through the eyepiece module, thereby achieving effective image transmission and presentation, providing users with clear and observable images, and meeting diverse observation needs.

[0010] Optionally, the image receiving component includes an image sensor and a wavelength selector. The image sensor and the wavelength selector are respectively disposed within the main body along the first optical axis. The wavelength selector is located between the image sensor and the dichroic mirror. The image sensor is electrically connected to the processor.

[0011] By employing the above technical solution, a wavelength selector is positioned between the image sensor and the dichroic mirror, allowing for the selection of light wavelengths according to different needs. When light passes through the dichroic mirror and reaches the wavelength selector, the selector filters out light of suitable wavelengths for transmission to the image sensor, avoiding interference from other unnecessary wavelengths. This enables the image sensor to more accurately receive the required light for image capture. Simultaneously, the image sensor is electrically connected to the processor, enabling timely transmission of captured image information for processing. This improves the accuracy and efficiency of image capture, providing a more reliable foundation for subsequent image display and calibration operations.

[0012] Optionally, the projection component includes a microdisplay and a projection lens. The microdisplay and the projection lens are respectively disposed within the main body along the second optical axis. The projection lens is located between the microdisplay and the dichroic mirror. The microdisplay is electrically connected to the processor.

[0013] By adopting the above technical solution, the microdisplay and projection lens are arranged along the second optical axis within the main body, with the projection lens positioned between the microdisplay and the dichroic mirror. The microdisplay is electrically connected to the processor. The processor controls the microdisplay to display images, which are then projected onto the dichroic mirror via the projection lens. The dichroic mirror then transmits the images to the eyepiece module, realizing the image projection display function. This allows users to observe the images displayed on the microdisplay through the eyepiece module, providing a technical means for image projection for augmented reality telescopes. It enables a single device to switch between a mixed reality mode (optical background and digital AR information) and a pure digital photography mode with unobstructed optical paths, satisfying the needs of both immersive observation and high-quality astronomical photography scenarios.

[0014] Optionally, the projection assembly includes a reflector disposed within the main body. The reflector, the projection lens, and the microdisplay are sequentially arranged along a third optical axis, which is parallel to the first optical axis. The reflector is disposed between the dichroic mirror and the projection lens, and is used to reflect the light emitted from the projection lens along the second optical axis to the dichroic mirror.

[0015] By adopting the above technical solution, the third optical axis is set parallel to the first optical axis, and the reflector, projection lens, and microdisplay are set sequentially along the third optical axis. The reflector is located between the dichroic mirror and the projection lens, so that the light emitted from the projection lens can be reflected by the reflector along the second optical axis to the dichroic mirror. This realizes the function of transmitting the image obtained from the first optical axis to the eyepiece module via the image projection module along the second optical axis. The transmission path of the image in the telescope is optimized, the efficiency and accuracy of image projection are improved, and users are provided with a clearer and more accurate image observation experience.

[0016] Optionally, when the dichroic mirror is in the first position, the processor controls the microdisplay to display a first image captured by the image receiving component. The first image is then passed through the projection lens and the dichroic mirror to form a second image on the image receiving component. The processor calculates the deviation by comparing the first image and the second image and calibrates the augmented reality image displayed by the microdisplay based on the deviation.

[0017] By adopting the above technical solution, when the dichroic mirror is in the first position, the image receiving component captures the first image, and the processor controls the microdisplay to display the first image. This image, after passing through the projection lens and the dichroic mirror, forms a second image on the image receiving component. Due to various deviations in the actual optical system, there will be differences between the first and second images. By comparing these two images, the processor can calculate the deviation and calibrate the augmented reality image displayed on the microdisplay based on this deviation. This allows the augmented reality image to more accurately match the actual optical image, thereby improving the realism and accuracy of the augmented reality experience and solving the technical problem of misregistration caused by assembly errors between the optical and digital systems.

[0018] Optionally, the objective module includes a first driving member, an adjusting sleeve, a rear objective lens group, and a front objective lens group. The first driving member is disposed within the main body. The adjusting sleeve, the rear objective lens group, and the front objective lens group are all disposed along the first optical axis. The adjusting sleeve is slidably disposed within the main body and connected to the first driving member. The rear objective lens group is disposed between the adjusting sleeve and the dichroic mirror. The front objective lens group is disposed within the adjusting sleeve. The first driving member is used to drive the adjusting sleeve to move closer to or away from the rear objective lens group.

[0019] By adopting the above technical solution, the first driving component can drive the adjusting sleeve to slide along the first optical axis within the main body, so that the adjusting sleeve moves closer to or further away from the rear objective lens group. This facilitates changing the relative position between the front and rear objective lens groups, thereby adjusting the focal length of the objective lens module. After identifying celestial bodies, the focal length can be automatically adjusted to the optimal state, ensuring that both the background optical image and the infrared image captured by the image projection module achieve the highest clarity. This provides a guarantee for subsequent accurate calibration and high-quality observation, achieving a synergistic improvement in imaging quality and intelligent functions.

[0020] Optionally, a threaded sleeve is provided on the main body along the second optical axis, and the eyepiece module includes an eyepiece sleeve and an eyepiece. The eyepiece sleeve is threadedly connected to the threaded sleeve, and the eyepiece is coaxially disposed inside the eyepiece sleeve.

[0021] By adopting the above technical solution, the eyepiece sleeve is connected to the threaded sleeve by a threaded connection, which allows the position of the eyepiece in the second optical axis direction to be adjusted by rotating the eyepiece sleeve. This facilitates the synchronous change of the eyepiece position, thereby realizing the adjustment of the eyepiece focal length to meet the vision or observation needs of different users and improve the clarity of observation.

[0022] Optionally, a rotating shaft is rotatably connected inside the main body, the dichroic mirror is connected to the rotating shaft, and a second driving member is provided on the main body. The second driving member is connected to the rotating shaft and is used to drive the rotating shaft to rotate so that the dichroic mirror moves to the first position or the second position.

[0023] By adopting the above technical solution, the second driving component is connected to the rotating shaft, and the dichroic mirror is connected to the rotating shaft. When the second driving component drives the rotating shaft to rotate, it can drive the dichroic mirror to rotate, thereby moving the dichroic mirror to the first position or the second position. The first position and the second position correspond to different optical path structures, thereby enabling the augmented reality telescope to switch between different imaging modes to meet different usage needs.

[0024] Optionally, the first position is where the surface of the dichroic mirror forms a 45-degree angle with the first optical axis, and the second position is where the dichroic mirror is detached from the first optical axis and parallel to the first optical axis.

[0025] By adopting the above technical solution, the dichroic mirror can switch between a first position where the mirror surface forms a 45-degree angle with the first optical axis and a second position where it is detached from the first optical axis and parallel to the first optical axis. This allows the telescope to have two imaging modes. When the dichroic mirror is in the first position, a mixed reality imaging mode can be achieved. Infrared light collected by the objective lens module is imaged onto the image sensor to achieve infrared light image acquisition. Visible light collected by the objective lens module is reflected by the dichroic mirror and enters the eyepiece. In addition, part of the visible light emitted by the image projection module passes through the dichroic mirror onto the eyepiece. The two focal planes coincide near the entrance pupil of the eyepiece to achieve mixed reality imaging display. When the dichroic mirror is in the second position, a photographic imaging mode can be achieved. All the light from the objective lens module can reach the image projection module, and the light emitted by the image projection module can also reach the eyepiece, achieving the effect of displaying the image captured by the image sensor onto the eyepiece.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The dichroic mirror is movable and has a first and second position, allowing the telescope to have two imaging modes, solving the problem that traditional telescopes cannot simultaneously meet the needs of mixed reality imaging and photographic imaging, thus expanding the application scenarios and functions; 2. The processor can calculate the deviation by comparing the first image and the second image and calibrate the augmented reality image displayed on the microdisplay so that the augmented reality image can accurately overlap with the optical image.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses an augmented reality telescope.

[0034] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Reference Figure 1 , Figure 2 and Figure 3 An augmented reality telescope includes a main body 1, an objective lens module 2, an eyepiece module 3, and an image projection module 4. The objective lens module 2, eyepiece module 3, and image projection module 4 are respectively mounted on the main body 1. A movable dichroic mirror 11 is disposed within the main body 1, positioned between the objective lens module 2, eyepiece module 3, and image projection module 4. By adjusting the position of the dichroic mirror 11, users can switch between two imaging modes, thus meeting diverse observation needs.

[0036] Reference Figure 3 The main body 1 serves as the supporting structure for the entire augmented reality telescope. It is constructed using high-strength metallic materials, such as aluminum alloy, to ensure structural stability and durability. The main body 1 is equipped with a first optical axis 12, a second optical axis 13, and a third optical axis 14. The first optical axis 12 and the third optical axis 14 are parallel, and the second optical axis 13 forms an angle with and intersects the first optical axis 12. In this embodiment, the angle between the second optical axis 13 and the first optical axis 12 is 90 degrees to facilitate the reflection and refraction of light.

[0037] The objective lens module 2 includes a first drive unit 21, an adjustment sleeve 22, a rear objective lens group 23, and a front objective lens group 24. The first drive unit 21 and the rear objective lens group 23 are respectively disposed within the main body 1. The adjustment sleeve 22, the rear objective lens group 23, and the front objective lens group 24 are all arranged along the first optical axis 12. The adjustment sleeve 22 is slidably disposed within the main body 1 and connected to the first drive unit 21. The rear objective lens group 23 is located between the adjustment sleeve 22 and the dichroic mirror 11, and the front objective lens group 24 is disposed within the adjustment sleeve 22.

[0038] In this embodiment, the first driving component 21 is an electric focusing motor, which can precisely adjust the position of the adjusting sleeve 22 according to different imaging modes and observation requirements, thereby changing the distance between the front objective lens group 24 and the rear objective lens group 23 to achieve the focusing function.

[0039] The adjusting sleeve 22 is made of stainless steel. Its sliding within the main body 1 is achieved through the cooperation of a guide rail and a slider, ensuring the stability and precision of its movement. The rear objective lens group 23 uses a high-precision optical glass lens, capable of focusing and adjusting light to obtain a clear image. The front objective lens group 24 consists of multiple lenses with different focal lengths and curvatures. Through the combined action of these lenses, light is collected and converged, improving the telescope's observation capabilities.

[0040] The dichroic mirror 11 is made of glass with good optical properties and has a special optical film coated on its surface. This allows the dichroic mirror 11 to have different reflectivity and transmittance for different wavelengths of light. For example, it has high transmittance for near-infrared light with wavelengths greater than 700nm and high reflectivity for visible light in the 400-700nm range. At the same time, it also retains a specific low transmittance in the visible light range.

[0041] Reference Figure 3 and Figure 4 The dichroic mirror 11 has a first position and a second position. When the dichroic mirror 11 is in the first position, the mirror surface of the dichroic mirror 11 forms a 45-degree angle with the first optical axis 12, and at this time, the dichroic mirror 11 intersects with the first optical axis 12 and the second optical axis 13. When the dichroic mirror 11 is in the second position, the dichroic mirror 11 is detached from the first optical axis 12 and becomes parallel to the first optical axis 12, and at this time, the dichroic mirror 11 intersects with the second optical axis 13.

[0042] Reference Figure 1 and Figure 4A rotating shaft 15 is rotatably connected inside the main body 1. The dichroic mirror 11 is fixedly connected to the rotating shaft 15. A second driving member 16 is provided on the main body 1 and is connected to the rotating shaft 15. In this embodiment, the second driving member 16 is a micro motor to drive the rotating shaft 15 to rotate, thereby moving the dichroic mirror 11 to a first position or a second position. In other embodiments, the second driving member 16 can also be a handle to adjust the position of the dichroic mirror 11 by rotating the handle.

[0043] A threaded sleeve 17 is provided along the second optical axis 13 on the main body 1. The eyepiece module 3 includes an eyepiece sleeve 31 and an eyepiece 32. The eyepiece sleeve 31 is threadedly connected to the threaded sleeve 17, and the eyepiece 32 is coaxially disposed inside the eyepiece sleeve 31. The threaded connection between the eyepiece sleeve 31 and the threaded sleeve 17 allows for fine-tuning of the eyepiece 32 to meet the visual needs of different users. In this embodiment, the eyepiece 32 is a wide-angle eyepiece 32, which can provide a wider field of view and improve observation comfort.

[0044] Reference Figure 3 The image projection module 4 includes a processor 41, an image receiving component 42, and a projection component 43, all disposed within the main body 1. The image receiving component 42 includes an image sensor 421 and a wavelength selector 422. The image sensor 421 and the wavelength selector 422 are respectively disposed within the main body 1 along the first optical axis 12. The wavelength selector 422 is located between the image sensor 421 and the dichroic mirror 11. The image sensor 421 is electrically connected to the processor 41.

[0045] In this embodiment, the wavelength selector 422 is a dual-wavelength switcher, including a full-pass filter and an infrared cutoff filter, which can select the appropriate filter according to different imaging modes to obtain the best image effect. Furthermore, the image sensor 421 can be a high-resolution CMOS image sensor, capable of capturing clear images and transmitting the image signal to the processor 41.

[0046] The projection assembly 43 includes a microdisplay 431, a projection lens 432, and a reflector 433. The microdisplay 431, projection lens 432, and reflector 433 are sequentially arranged within the main body 1 along the third optical axis 14, with the reflector 433 located at the intersection of the third optical axis 14 and the second optical axis 13. The reflector 433 is positioned at a 45-degree angle to both the third optical axis 14 and the second optical axis 13. In this embodiment, the reflector 433 is a plane mirror with a highly reflective metal film coated on its surface to improve light reflection efficiency.

[0047] The projection lens 432 is located between the microdisplay 431 and the dichroic mirror 11, and the microdisplay 431 is electrically connected to the processor 41. In this embodiment, the microdisplay 431 is an OLED microdisplay, which features high contrast, high brightness, and fast response. The projection lens 432 uses a high-precision optical lens, which can clearly project the optical image generated by the microdisplay 431 onto the reflector 433.

[0048] The light emitted by the microdisplay 431, after passing through the projection lens 432, propagates along the third optical axis 14, is reflected 90 degrees by the reflector 433, and then travels along the second optical axis 13 to the dichroic mirror 11, before passing through the dichroic mirror 11 and entering the object-side focal plane of the eyepiece 32. This design allows the length of the projection assembly 43 to be arranged parallel to the length of the main body 1, effectively reducing the size of the telescope along the second optical axis 13 and making the overall structure more compact.

[0049] In another preferred embodiment, the reflector 433 may be omitted, and the microdisplay 431 and the projection lens 432 may be directly arranged along the second optical axis 13, so that the light emitted by the microdisplay 431 can be directly incident on the dichroic mirror 11 after passing through the projection lens 432, thereby reducing the number of parts required for the telescope and reducing production costs.

[0050] The implementation principle of an augmented reality telescope according to an embodiment of this application is as follows: In mixed reality imaging mode, the dichroic mirror 11 is in the first position. Light from distant celestial objects passes through the front objective lens group 24 and enters the dichroic mirror 11 along the first optical axis 12 and the rear objective lens group 23. The visible light portion of the light is efficiently reflected by the dichroic mirror 11, deflected by 90 degrees, and then enters the eyepiece 32 along the second optical axis 13, where it is observed by the human eye, forming an optical background field of view. The near-infrared portion of the light penetrates the dichroic mirror 11 and continues to travel along the first optical axis 12, passing through the wavelength selector 422 (which switches to a filter that allows infrared light to pass through), and finally is imaged on the image sensor 421 to form an infrared digital image.

[0051] The processor 41 acquires infrared digital images and analyzes them (e.g., identifying constellations and celestial bodies), or combines them with internally stored star map data to generate augmented reality information (e.g., celestial body names, constellation connections, orbits, etc.). The processor 41 controls the microdisplay 431 to display this augmented reality information. This information image, after being shaped by the projection lens 432, is projected along the third optical axis 14 onto the reflector 433, reflected 90 degrees by the reflector 433, and then projected along the second optical axis 13 onto the dichroic mirror 11. Because the dichroic mirror 11 has a certain transmittance for visible light, part of the digital image is transmitted through the dichroic mirror 11 and superimposed with the visible light background image reflected from the front near the focal plane of the eyepiece 32, ultimately being seen by the human eye simultaneously. This achieves the fusion observation of optical scenes and digital information.

[0052] In photographic imaging mode, the dichroic mirror 11 is in its second position. Light from distant celestial bodies passes through the front objective lens group 24 and travels directly along the first optical axis 12 without obstruction. The processor 41 controls the wavelength selector 422 to switch to a visible light filter (such as an infrared cutoff filter) to obtain a color image that conforms to human vision. All the light eventually reaches the image sensor 421 for imaging, allowing the user to obtain high-quality digital photos or videos. At this time, the processor 41 can transmit the real-time image captured by the image sensor 421 to the microdisplay 431. The microdisplay 431 reshapes the image through the projection lens 432 and projects it onto the reflector 433. The image is reflected 90 degrees by the reflector 433 and then travels along the second optical axis 13 towards the dichroic mirror 11, passing through the dichroic mirror 11 and entering the eyepiece 32, allowing the user to perform electronic framing through the eyepiece 32 or output the image to an external device.

[0053] Furthermore, in mixed reality imaging mode, to ensure precise alignment between digital information and optical images, this telescope can perform a self-calibration procedure. First, when the dichroic mirror 11 is in the first position, the processor 41 temporarily shuts down the display of the microdisplay 431, allowing the image sensor 421 to capture only the real infrared image of the celestial object passing through the objective lens module 2; this image is defined as the "first image." Subsequently, the processor 41 sends this "first image" to the microdisplay 431 and instructs it to display it as is. This image emitted by the microdisplay 431, after passing through the projection lens 432, the reflector 433, and the dichroic mirror 11, has a portion of its light re-entering the image sensor 421 and forming an image. The image formed on the image sensor 421 at this time is defined as the "second image."

[0054] Finally, the processor 41 uses image processing algorithms such as feature point matching to accurately compare the position, angle, and size differences of the same features (such as star points) on the "first image" and the "second image." By calculating the pixel coordinate offset, rotation angle, and scaling ratio of the corresponding feature points, it generates an affine transformation matrix as a deviation transformation matrix. In subsequent normal use, the processor will use this deviation transformation matrix to pre-correct the image before displaying any augmented reality image, ensuring that the digital information ultimately projected to the user's eye can achieve pixel-level precise overlap with the optical field of view. This improves the realism and accuracy of the augmented reality experience and solves the technical problem of misregistration caused by assembly errors between the optical and digital systems.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
