Description

Technical Field

[0001] This invention belongs to the field of space optical low-light imaging technology, specifically relating to a high-precision coupling and alignment device for an image intensifier and a detector. Background Technology

[0002] Low-light imaging technology, as one of the core technologies for target detection in low-light environments, uses an image intensifier to amplify the energy of weak light signals, which can transform targets with extremely low visibility into clear images that can be observed by the naked eye, thus making up for the limitations of observation in low-light conditions.

[0003] Since the coupling accuracy between the image intensifier and the detector photosensitive surface not only determines the final imaging effect, but also the detector photosensitive surface is exposed during the coupling assembly process, even a slight deviation may damage the detector photosensitive surface or break the detector gold wire.

[0004] Currently, there is no professional image intensifier and detector coupling equipment. Most rely on manual coupling, which results in low alignment accuracy and can easily damage the detector during the coupling and alignment process. Summary of the Invention

[0005] The technical problem this invention aims to solve is to address the shortcomings of the prior art by providing a high-precision coupling and alignment device for an image intensifier and a detector. This device utilizes a detector pose adjustment module and an image intensifier pose adjustment module to achieve independent pose adjustment of the detector and the image intensifier. While ensuring alignment, they are then moved relative to each other for high-precision coupling. This solves the technical problem in the prior art where traditional coupling processes easily damage the detector's optical surface or break the detector's gold wires.

The detector pose adjustment module is used to drive the detector to adjust in four dimensions: Rx1, Ry1, Rz1 and Z axis. The image intensifier pose adjustment module is used to drive the image intensifier to adjust in six dimensions (Rx2, Ry2, Rz2 and X-axis, Y-axis, Z-axis) relative to the internal detector pose adjustment module, so as to couple and align the image intensifier with the detector.

[0011] Preferably, the image intensifier pose adjustment module includes a mounting base, an XY translation platform, and a second multi-degree-of-freedom platform arranged sequentially from bottom to top. The XY translation platform is a hollow structure with a central opening, and the detector pose adjustment module is assembled with the mounting base through the central opening of the XY translation platform. The XY translation platform is used to drive the second multi-degree-of-freedom platform to adjust the X-axis and Y-axis dimensions, and the second multi-degree-of-freedom platform is used to drive the image intensifier to adjust the Rx2, Ry2, Rz2 and Z-axis dimensions.

[0012] Preferably, the second multi-degree-of-freedom platform includes a second lifting mechanism, a hollow base, and a hollow turntable. The second lifting mechanism is arranged in three groups in a circular array along the axis of the central turntable at the upper end of the XY translation platform. The upper end of the second lifting mechanism is ball-jointed with the lower end of the hollow base. The hollow turntable is installed on the hollow base and is used to drive the image intensifier to perform Rz2 dimension adjustment.

[0013] Preferably, the second lifting mechanism includes a linear motor, a second lifting mechanism slider, and a second load balancing cylinder. The lower end of the second lifting mechanism slider is assembled with the output end of the linear motor, the upper end of the second lifting mechanism slider is ball-jointed with the hollow base, the second lifting slider and the cylinder body of the second load balancing cylinder are slidably engaged along the Z-axis, and the upper part of the second lifting mechanism is connected to the output end of the second load balancing cylinder.

[0014] Preferably, the upper end of the slider of the second lifting mechanism is provided with a second ball joint support. The second ball joint support includes a second bottom support and a second sliding seat that are slidably engaged. The sliding direction of the second sliding seat extends radially along the hollow turntable. The upper end of the second sliding seat is provided with a second ball joint mechanism.

[0015] Preferably, the XY translation platform includes an X-axis platform and a Y-axis platform, the X-axis platform being slidably mounted on the mounting base along the X-axis direction, and the Y-axis platform being slidably mounted on the X-axis platform along the Y-axis direction.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: A nested detector pose adjustment module and image intensifier pose adjustment module form a dual independent parallel adjustment mechanism. The detector is mounted on the internal detector pose adjustment module. This module adjusts the detector in the Rx1 and Ry1 dimensions to achieve horizontal adjustment, in the Rz1 dimension to achieve angular adjustment, and in the Z-axis dimension to achieve height adjustment. In this way, the detector pose adjustment module adjusts the detector in four dimensions (Rx1, Ry1, Rz1, and Z-axis) to achieve reference positioning.

[0017] The image intensifier is mounted on the image intensifier pose adjustment module. This module adjusts the image intensifier relative to the detector pose adjustment module in Rx2 and Ry2 dimensions to achieve leveling, ensuring the image intensifier is parallel to the detector's photosensitive surface. Next, the module adjusts the image intensifier in Rz2 dimension, causing it to horizontally spin relative to the detector reference. Finally, the module adjusts the image intensifier in the X and Y axes, causing it to shift relative to the detector reference along the X and Y axes, achieving alignment between the image intensifier and the detector. Finally, the module adjusts the image intensifier in the Z-axis, causing it to shift relative to the detector reference along the Z-axis, slowly lowering it until it is fully aligned with the detector, achieving coupling and alignment between the two.

[0018] Therefore, by dividing the detector pose adjustment module and the image intensifier pose adjustment module into a nested layout, this application forms a dual independent parallel adjustment mechanism, which can achieve rapid coupling and alignment of the image intensifier and the detector, and avoid the risk of damage to the detector photosensitive surface or breakage of the detector gold wire caused by traditional coupling processes.

[0019] Furthermore, the bottom turntable facilitates the adjustment of the Rz1 dimension, and the first multi-degree-of-freedom platform facilitates the adjustment of the Rx1, Ry1 and Z-axis dimensions.

[0020] Furthermore, the first multi-degree-of-freedom platform adopts three sets of first lifting mechanisms to form a three-axis mechanism, realizing three-point leveling and facilitating control and adjustment accuracy.

[0021] Furthermore, by utilizing the high precision and fast response speed of the voice coil motor, rapid adjustment of the detector is achieved. The first load balancing cylinder provides stable support through piston air flotation, eliminating the defect of low load of the voice coil motor in vertical applications.

[0022] Furthermore, the ball joint support includes a bottom support and a sliding seat that slide against each other, and the sliding direction extends radially along the bottom turntable. The ball joint mechanism is set on the sliding seat. During the adjustment process, the sliding seat is used to eliminate the X and Y components generated by the detector pose adjustment module during the adjustment of the Rx1 and Ry1 dimensions.

[0023] Furthermore, the XY translation platform has a hollow structure, which facilitates the installation of the detector pose adjustment module on the mounting base, realizing the nested arrangement of the detector pose adjustment and image intensifier pose adjustment modules. The XY translation platform can drive the second multi-degree-of-freedom mechanism to move along the X and Y axes, completing the adjustment of the X and Y axis dimensions of the image intensifier. The second multi-degree-of-freedom platform facilitates the adjustment of the Rx2, Ry2, Rz2, and Z axis dimensions of the image intensifier.

[0024] Furthermore, the second multi-degree-of-freedom platform employs three sets of second lifting mechanisms to form a three-axis mechanism, achieving three-point leveling and realizing the Rx2, Ry2, and Z-axis dimensions of the image intensifier, while facilitating control of adjustment accuracy. The Rz2 dimension adjustment of the image intensifier is completed using the hollow turntable at the top.

[0025] Furthermore, by utilizing the high precision and fast response of linear motors, rapid adjustment of the image intensifier can be achieved. The second load balancing cylinder provides stable support through piston air flotation, eliminating the limitation of linear motors in terms of low load in vertical applications.

[0026] Furthermore, by utilizing a ball joint support consisting of a bottom support and a sliding seat, the sliding seat is used to eliminate the X and Y components generated by the image intensifier pose adjustment module during the adjustment process in the Rx2 and Ry2 dimensions.

[0027] Furthermore, the XY translation platform adopts a layered sliding design, which makes the X-axis and Y-axis translation adjustments of the image intensifier independent of each other and without interference.

[0028] In summary, the high-precision coupling and alignment device for the image intensifier and detector in this invention can directly couple the detector at the output end of the image intensifier. Through this coupling and alignment device, the pose adjustment and reference alignment of the image intensifier and detector are realized, thereby achieving high-precision coupling between the image intensifier and detector.

[0040] The present invention provides a high-precision coupling and alignment device for an image intensifier and a detector, which can directly couple the detector 3 at the output end of the image intensifier 5 to realize the pose adjustment and reference alignment of the image intensifier 5 and the detector 3, thereby achieving high-precision coupling between the image intensifier 5 and the detector 3.

[0041] Please see Figures 1 to 8 As shown, this invention discloses a high-precision coupling and alignment device for an image intensifier and a detector, comprising a detector pose adjustment module 2 and an image intensifier pose adjustment module 1. The detector pose adjustment module 2 is nested within the image intensifier pose adjustment module 1. The detector pose adjustment module 2 is used to drive the detector 3 to perform Rx1, Ry1, Rz1, and Z-axis dimensional adjustments. The image intensifier pose adjustment module 1 is used to drive the image intensifier 5 to perform Rx2, Ry2, Rz2, and X-axis, Y-axis, and Z-axis dimensional adjustments relative to the internal detector pose adjustment module 2, thereby achieving coupling and alignment between the image intensifier 5 and the detector 3.

[0042] In this embodiment, Rx, Ry, and Rz represent rotations about the X-axis, Y-axis, and Z-axis, respectively. Dimensional adjustments along the X-axis, Y-axis, and Z-axis represent movements along the X-axis, Y-axis, and Z-axis, respectively.

[0043] In practical use, the nested detector pose adjustment module 2 and image intensifier pose adjustment module 1 form a dual independent parallel adjustment mechanism. The detector 3 is mounted on the internal detector pose adjustment module 2. The detector pose adjustment module 2 drives the detector 3 to perform adjustments in the Rx1 and Ry1 dimensions to adjust its horizontal position. It also drives the detector 3 to perform adjustments in the Rz1 dimension to adjust its angular position and in the Z-axis dimension to adjust its height. Thus, by using the detector pose adjustment module 2 to adjust the detector 3 in four dimensions (Rx1, Ry1, Rz1, and Z-axis), the reference point is established.

[0044] Image intensifier 5 is mounted on image intensifier pose adjustment module 1. Image intensifier pose adjustment module 1 drives image intensifier 5 to perform Rx2 and Ry2 dimensional adjustments relative to detector pose adjustment module 2 for leveling, making image intensifier 5 parallel to the photosensitive surface of detector 3. Image intensifier pose adjustment module 1 then performs Rz2 dimensional adjustments, driving image intensifier 5 to perform horizontal spin adjustments relative to detector 3. Image intensifier pose adjustment module 1 also performs X-axis and Y-axis dimensional adjustments, driving image intensifier 5 to perform X-axis and Y-axis displacement adjustments relative to detector 3, achieving alignment between image intensifier 5 and detector 3. Finally, image intensifier pose adjustment module 1 performs Z-axis dimensional adjustments, driving image intensifier 5 to perform Z-axis displacement adjustments relative to detector 3. Image intensifier 5 then slowly descends relative to detector 3 along the Z-axis until it is completely in contact with detector 3, achieving coupling alignment between image intensifier 5 and detector 3.

[0045] Therefore, the image intensifier 5 and the detector 3 need to be adjusted independently in terms of level and angle, and the two need to coincide in the Z-axis direction. Therefore, this application divides the image intensifier 5 into a detector pose adjustment module 2 and an image intensifier pose adjustment module 1, and adopts a nested layout to form a dual independent and non-interfering parallel adjustment mechanism. This enables the rapid coupling and alignment of the image intensifier 5 and the detector 3, and avoids the risk of damage to the photosensitive surface of the detector 3 or breakage of the gold wire of the detector 3 caused by the traditional coupling process.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0047] Please see Figures 1 to 8 In the high-precision coupling and alignment device for image intensifier and detector of the present invention, such as Figure 2 As shown, the detector pose adjustment module 2 includes a bottom turntable 2-1, and a first multi-degree-of-freedom platform is provided at the upper end of the bottom turntable 2-1. The detector 3 is arranged on the first multi-degree-of-freedom platform. The bottom turntable 2-1 is used to drive the detector 3 to perform Rz1 dimension adjustment.

[0048] The first multi-degree-of-freedom platform is used to drive detector 3 to adjust its Rx1, Ry1, and Z-axis dimensions. Specifically, for example... Figure 2 , 3 As shown, the first multi-degree-of-freedom platform includes a first lifting mechanism 2-2 and a detector connecting platform 2-3. Three sets of the first lifting mechanisms 2-2 are arranged in a circular array along the rotation axis of the bottom turntable 2-1. The upper end of the first lifting mechanism 2-2 engages with the bottom ball joint of the detector connecting platform 2-3, forming a three-axis mechanism. The three sets of first lifting mechanisms 2-2 are used to drive the detector 3 to adjust its Rx1, Ry1, and Z-axis dimensions. The detector connecting platform 2-3 has mounting holes at its center that fit the detector 3. The detector 3 is mounted onto the detector connecting platform 2-3 via a circuit board 4. Three-point leveling is used to achieve adjustment of the detector 3's Rx1, Ry1, and Z-axis dimensions.

[0049] Specifically, in this embodiment, the first lifting mechanism 2-2 includes a voice coil motor 2-2-1, a first lifting mechanism slider 2-2-2, a first sliding track 2-2-3, a first load balancing cylinder 2-2-4, and a first lifting mechanism absolute value grating ruler 2-2-5.

[0050] The lower ends of the voice coil motor 2-2-1 and the first load balancing cylinder 2-2-4 are fixed on the bottom turntable 2-1. The lower end of the slider 2-2-2 of the first lifting mechanism is assembled with the output end of the voice coil motor 2-2-1. The upper end of the slider 2-2-2 of the first lifting mechanism is ball-jointed with the detector connection platform 2-3.

[0051] The slider 2-2-2 of the first lifting mechanism slides in conjunction with the cylinder body of the first load balancing cylinder 2-2-4 via the first sliding guide rail 2-2-3. The upper piston of the first load balancing cylinder 2-2-4 is the output end, and the piston is connected and assembled with the slider 2-2-2 of the first lifting mechanism via a dovetail groove.

[0052] The absolute value grating ruler 2-2-5 of the first lifting mechanism collects the displacement data of the slider 2-2-2 of the first lifting mechanism in real time and feeds it back to the control unit to form a closed-loop control circuit, ensuring that the action response of each first lifting mechanism 2-2 is rapid and the position movement is accurate.

[0053] Utilizing the high precision and fast response speed of the voice coil motor 2-2-1, rapid and accurate adjustment of the detector's 3-position orientation is achieved. The first load balancing cylinder 2-2-4 uses a piston air-bearing method to provide support, keeping the load of the voice coil motor 2-2-1 in a suspended state. This eliminates the limitation of the voice coil motor 2-2-1 having a small load capacity in vertical applications, giving the first lifting mechanism 2-2 the characteristics of high action precision, fast response speed, and strong load capacity.

[0054] like Figure 3 As shown, in this embodiment, the slider 2-2-2 of the first lifting mechanism is ball-jointed with the detector connection platform 2-3 via a first ball joint support 2-3 at its upper end. Specifically, the first ball joint support 2-3 includes a first bottom support 2-3-1 and a first sliding seat 2-3-2 that are in sliding engagement. The sliding direction of the first sliding seat 2-3-2 extends radially along the bottom turntable 2-1, and a first ball joint mechanism 2-3-3 is provided at the upper end of the first sliding seat 2-3-2. The ball joint mechanism 2-3-3 is used to achieve the ball joint engagement between the first sliding seat 2-3-2 and the detector connection platform 2-3.

[0055] When the detector 3 is adjusted in the Rx1 and Ry1 dimensions using the three sets of first lifting mechanisms 2-2, the position center of the detector 3 will have relative displacement in the X and Y directions, generating X and Y components. Using the first ball joint support 2-3, which is composed of the first sliding seat 2-3-2 and the first bottom support 2-3-1, the first sliding seat 2-3-2 can slide away from the direction in which the detector 3 rotates during the adjustment process, thereby eliminating the X and Y components generated by the detector pose adjustment module 2 during the Rx1 and Ry1 dimension adjustment.

[0056] In this embodiment, as Figure 4 , 5As shown in Figure 6, the image intensifier pose adjustment module 1 includes, from bottom to top, a mounting base 1-1-3, an XY translation platform 1-1, and a second multi-degree-of-freedom platform. The XY translation platform 1-1 is used to drive the image intensifier 5 to perform X-axis and Y-axis dimensional adjustments, and the second multi-degree-of-freedom platform is used to drive the image intensifier 5 to perform Rx2, Ry2, Rz2, and Z-axis dimensional adjustments.

[0057] like Figure 5 As shown, the XY translation platform 1-1 includes an X-axis platform 1-1-5 and a Y-axis platform 1-1-6. The X-axis platform 1-1-5 is slidably mounted on the mounting base 1-1-3 along the X-axis direction and is driven by an X-axis translation mechanism. The Y-axis platform 1-1-6 is slidably mounted on the X-axis platform 1-1-5 along the Y-axis direction and is driven by a Y-axis translation mechanism.

[0058] Specifically, the Y-axis platform 1-1-6 is slidably mounted on the X-axis platform 1-1-5 via two intersecting guide rails 1-1-2 arranged symmetrically along the X-axis and extending along the Y-axis. The Y-axis translation mechanism includes a Y-axis drive motor 1-1-10, a connecting block 1-1-1, and a Y-axis platform absolute grating ruler 1-1-9. The Y-axis drive motor 1-1-10 is mounted on the side of the X-axis platform and is connected to the Y-axis platform 1-1-6 via the connecting block 1-1-1. The Y-axis drive motor 1-1-10 is a linear motor, which, together with the Y-axis platform absolute grating ruler 1-1-9, enables precise movement of the Y-axis platform 1-1-6 in the Y-axis direction.

[0059] The X-axis platform 1-1-5 is slidably mounted on the mounting base 1-1-3 via two intersecting guide rails 1-1-2 arranged symmetrically along the Y-axis and extending along the X-axis. The X-axis translation mechanism includes an X-axis drive motor 1-1-8, a connecting block 1-1-1, and an absolute grating ruler for the X-axis platform 1-1-7. The X-axis drive motor 1-1-8 is mounted on the side of the mounting base 1-1-3 and is connected to the mounting base 1-1-3 via the connecting block 1-1-1. The X-axis drive motor 1-1-8 is a linear motor, which, together with the absolute grating ruler for the X-axis platform 1-1-7, enables precise movement of the X-axis platform in the X-axis direction.

[0060] like Figure 5 As shown, both the X-axis platform 1-1-5 and the Y-axis platform 1-1-6 have through holes in their centers. The XY translation platform 1-1 forms a hollow structure with a central hole. An upwardly extending mounting platform 1-1-4 is provided in the center of the mounting base 1-1-3. Adjustment allowance is left between the mounting platform 1-1-4 and the central holes of the X-axis platform 1-1-5 and the Y-axis platform 1-1-6.

[0061] like Figure 1As shown, the detector pose adjustment module 2 is mounted on the mounting base 1-1-3 via the mounting platform 1-1-4, and the second multi-degree-of-freedom platform is mounted on the Y-axis platform, so that the detector pose adjustment module 2 and the image intensifier pose adjustment module 1 form a nested dual independent adjustment mechanism.

[0062] like Figure 6 As shown, in this embodiment, the second multi-degree-of-freedom platform includes a second lifting mechanism 1-2, a hollow base 1-4, and a hollow turntable 1-5. Three sets of the second lifting mechanisms 1-2 are arranged in a circular array along the axis of the central turntable 1-5 at the upper end of the Y-axis platform 1-1-6. The upper end of the second lifting mechanism 1-2 is ball-jointed with the lower end of the hollow base 1-4, and the three sets of second lifting mechanisms 1-2 drive the image intensifier to adjust the Rx2, Ry2, and Z-axis dimensions.

[0063] Hollow turntable 1-5 is mounted on hollow base 1-4, and image intensifier 5 is mounted on hollow turntable 1-5. Hollow turntable 1-5 drives image intensifier 5 to perform Rz2 dimension adjustment.

[0064] Specifically, in this embodiment, such as Figure 6 As shown, the second lifting mechanism 1-2 includes a linear motor 1-2-1, a second lifting mechanism slider 1-2-2, a second sliding guide rail 1-2-3, a second load balancing cylinder 1-2-4, and a second lifting mechanism absolute value grating ruler 1-2-5.

[0065] The lower ends of the linear motor 1-2-1 and the second load balancing cylinder 1-2-4 are fixed on the Y-axis platform. The lower end of the second lifting mechanism is assembled with the output end of the linear motor 1-2-4, and the upper end of the slider 1-2-2 of the second lifting mechanism is ball-jointed with the hollow base 1-4.

[0066] like Figure 6 As shown, the second lifting mechanism slider 1-2-2 slides in conjunction with the cylinder body of the second load balancing cylinder 1-2-4 via the second sliding guide rail 1-2-3. The upper piston of the second load balancing cylinder 1-2-4 is the output end, and the piston is connected and assembled with the second lifting mechanism slider 1-2-2 via a dovetail groove.

[0067] The absolute value grating ruler 1-2-5 of the second lifting mechanism collects the displacement data of the slider 1-2-2 of the second lifting mechanism in real time and feeds it back to the control unit to form a closed-loop control circuit, ensuring that the action response of each second lifting mechanism 1-2 is rapid and the position movement is accurate.

[0068] Utilizing the high precision and fast response of linear motor 1-2-1, rapid and accurate adjustment of the image intensifier's 5-position pose is achieved. The second load balancing cylinder 1-2-4 uses a piston air-bearing method to provide support, keeping the load of linear motor 1-2-1 in a suspended state. This eliminates the limitation of linear motor 1-2-1 having a small load capacity in vertical applications, giving the first lifting mechanism 2-2 the characteristics of high motion precision, fast response speed, and strong load capacity.

[0069] Preferably, in this embodiment, the second lifting mechanism slider 1-2-2 is ball-jointed with the hollow base 1-4 via the second ball joint support 1-3 at the upper end.

[0070] The second ball joint support 1-3 includes a slidingly fitted second bottom support 1-3-1 and a second sliding seat 1-3-2. The sliding direction of the second sliding seat 1-3-2 extends radially along the hollow base 1-4. A second ball joint mechanism 1-3-3 is provided at the upper end of the second sliding seat 1-3-2. The ball joint mechanism 1-3-3 enables the second sliding seat 1-3-2 to engage with the hollow base 1-4.

[0071] When the detector 3 is adjusted in the Rx2 and Ry2 dimensions using the three sets of second lifting mechanisms 1-2, the center of the detector 3 will experience relative displacement in the X and Y directions, generating X and Y components. Using the second ball joint support 1-3, which is composed of the second sliding seat 1-3-2 and the second bottom support 1-3-1, the second sliding seat 1-3-2 can slide away from the image intensifier 5 during the adjustment process, thus eliminating the X and Y components generated by the image intensifier pose adjustment module 1 during the Rx2 and Ry2 dimension adjustment. This facilitates the coupling and alignment of the image intensifier 5 and the detector 3.

[0072] like Figure 4 As shown, the hollow turntable 1-5 includes a hollow turntable outer ring 1-5-1, a hollow turntable inner ring 1-5-2, a hollow turntable drive mechanism 1-5-3, and a hollow turntable absolute value grating ruler 1-5-4. The hollow turntable inner ring 1-5-2 is fixed to the hollow base 1-5. The hollow turntable outer ring 1-5-1 rotates in conjunction with the inner ring 1-5-2. The hollow turntable drive mechanism 1-5-3 drives the hollow turntable outer ring 1-5-1 to rotate relative to the hollow turntable inner ring 1-5-2. The hollow turntable absolute value grating ruler 1-5-4 is arranged at the circumference of the outer ring.

[0073] like Figure 8 As shown, the image intensifier 5 is fixedly mounted on the outer ring 1-5-1 of the hollow turntable via the adapter 6. The hollow turntable drive mechanism 1-5-3, together with the absolute value grating ruler 1-5-4 of the hollow turntable, drives the outer ring 1-5-1 of the hollow turntable to rotate, thereby realizing the Rz2 dimension adjustment of the image intensifier 5.

[0074] The method of using the high-precision coupling and alignment device for image intensifier and detector of the present invention is as follows: The detector 3 is mounted on the detector connection platform 2-3 via the circuit board 4, completing the assembly of the detector 3 and the detector pose adjustment module 2. The image intensifier 5 is mounted on the inner mounting ring 1-3-2 via the adapter 6, completing the assembly of the image intensifier 5 and the image intensifier pose adjustment module 1.

[0075] According to the attitude requirements, the detector pose adjustment module 2 drives the detector 3 to adjust the Rx1, Ry1 and Rz1 dimensions through the photosensitive surface mark of the detector 3, and performs reference extraction.

[0076] Based on the aforementioned detector 3 reference, the image intensifier pose adjustment module 1 drives the image intensifier 5 to perform Rx1 and Ry1 dimension adjustments via the second multi-degree-of-freedom platform, leveling the image intensifier 5 so that it is parallel to the detector 3. Then, through the XY translation platform 1-1 and the hollow turntable 1-5, the image intensifier 5 is driven to perform XY displacement and spin adjustment relative to the detector 3 reference, completing the reference alignment between the image intensifier 5 and the detector 3.

[0077] After the image intensifier 5 and the detector 3 are aligned, the second multi-degree-of-freedom platform slowly lowers the image intensifier 5 until the image intensifier 5 and the detector 3 are completely in contact, thus completing the alignment and coupling of the image intensifier 5 and the detector 3.

[0078] In summary, the high-precision coupling and alignment device for image intensifier and detector of the present invention uses two pairs of three-axis mechanisms to improve the leveling accuracy of detector 3 and image intensifier 5, facilitating reference extraction and alignment. The independent adjustment of image intensifier 5 and detector 3 is achieved using detector pose adjustment module 2 and image intensifier pose adjustment module 1. The detector pose adjustment module 2 and image intensifier pose adjustment module 1 form a nested structure, facilitating the XY-axis translation and spin adjustment of image intensifier 5 relative to detector 3, completing high-precision reference alignment and coupling of image intensifier 5 and detector 3 based on detector 3 reference. Simultaneously, the coupling and alignment device of this application enables rapid coupling and alignment of image intensifier 5 and detector 3, effectively avoiding the risk of damage to the optical surface of detector 3 or breakage of the gold wire of detector 3 caused by traditional coupling processes, and achieving batch coupling of image intensifier 5 and detector 3 within a limited time.

Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of the claims of this invention.
