Description

Technical Field

[0001] This invention relates to the field of optical instrument technology, and in particular to a quantum optical path adaptive alignment compensation mechanism. Background Technology

[0002] Quantum optical path adaptive alignment compensation mechanisms, as an important type of optical adjustment device, are widely used in scenarios that rely on precise optical path transmission, such as quantum communication, quantum computing, and quantum sensing. Their core purpose is to achieve precise alignment and offset compensation of quantum beams. By adjusting the position and angle of optical components, they correct environmental interference, structural assembly errors, and optical path offsets generated during beam transmission, ensuring stable transmission of quantum signals, reducing quantum state decoherence, and ensuring the overall performance and reliability of the quantum system. However, existing technologies still have the following problems: Existing alignment compensation mechanisms for quantum optical paths mostly adopt a single angle adjustment mode, which does not take into account the actual need for secondary fine adjustment after the quantum optical path is turned. This results in the inability to correct the small angle deviations generated after the optical path is turned. In addition, there are common interference factors in the application scenarios of quantum optical paths, such as changes in ambient temperature and slight vibrations of equipment. These interferences can cause optical components such as reflectors and dimming components to deflect on their own, destroying the calibrated optical path angle and making it impossible to maintain alignment accuracy for a long time.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a quantum optical path adaptive alignment compensation mechanism, including a light source 4. The light source 4 is mounted on a coarse adjustment device. The light source 4 serves as the quantum beam emission source. The light source 4 is mounted on top of the coarse adjustment device. The coarse adjustment device is used to achieve large-range coarse adjustment of the position of the light source 4 in a two-dimensional plane.

[0033] A light guide chamber 3 is installed at the light emission point of the light source component 4. The light guide chamber 3 is used to constrain and guide the transmission path of the quantum beam emitted by the light source component 4 and to provide an installation position for the subsequent optical path angle adjustment structure.

[0034] Specifically, the coarse adjustment device includes a lateral movement component 1, which includes a crossbeam 11. A timing belt 12 is fixedly installed at both ends of the groove on the top surface of the crossbeam 11 via a fixing bracket 13. The fixing bracket 13 limits and tensions the timing belt 12. A movable clamping plate 14 is provided on the side wall of the crossbeam 11. A servo motor 17 is fixedly installed on the side wall of the movable clamping plate 14. The output shaft of the servo motor 17 is keyed to a timing pulley 18. The timing pulley 18 meshes with the side wall of the timing belt 12. Pressure rollers 16 roll on the surface of the timing belt 12 located on both sides of the timing pulley 18, which can limit and press the timing belt 12, ensuring the stability of the meshing transmission between the timing pulley 18 and the timing belt 12, and preventing transmission deviation and gap sway. The interior of the pressure roller 16 is rotatably connected to a connecting rod 15, which is fixedly installed on both sides of the movable clamping plate 14.

[0035] Servo motor 17 drives synchronous pulley 18 on the output shaft to rotate. Synchronous pulley 18 meshes with synchronous belt 12 to form a synchronous belt transmission pair. Pressure rollers 16 on both sides of synchronous pulley 18 are fixed to movable clamping plate 14 via connecting rod 15. They can press synchronous belt 12 from the outside, limiting the radial runout and lateral offset of synchronous belt 12, ensuring smooth and uninterrupted meshing transmission between synchronous pulley 18 and synchronous belt 12. Servo motor 17 can drive movable clamping plate 14 to make precise lateral linear displacement along crossbeam 11 by rotating forward and reverse, realizing coarse adjustment of the lateral position of the whole machine.

[0036] The coarse adjustment device also includes a longitudinal moving component 2, which includes a longitudinal beam 21. Both ends of the longitudinal beam 21 are fixedly installed on the side walls of the moving clamp 14, and can move laterally synchronously with the transverse moving component 1. A synchronous belt 22 is installed in the groove on the top surface of the longitudinal beam 21. A moving clamp 23 is provided on one side wall of the longitudinal beam 21. A servo motor 24 is installed on the side wall of the moving clamp 23. The output shaft of the servo motor 24 is keyed to a synchronous wheel 25. The synchronous wheel 25 is meshed with the side wall of the synchronous belt 22. Pressure rollers 28 roll on the surface of the synchronous belt 22 located on both sides of the synchronous wheel 25. The inside of the pressure roller 28 is rotatably installed with the connecting rod 27. One end of the connecting rod 27 is fixedly installed on both sides of the moving clamp 23. The other end of the connecting rod 27 is fixedly installed with a mounting plate 26. The mounting plate 26 serves as a support mounting base for the light source 4 and the light guide chamber 3. Servo motor 24 drives synchronous pulley 25 to mesh with synchronous belt 22. The pressure rollers 28 on both sides are fixed on the movable clamping plate 23 through connecting rod 27, which can press and limit the synchronous belt 22 and prevent it from running off-center. The operation of servo motor 24 can drive mounting plate 26 to make longitudinal linear displacement along longitudinal beam 21, which cooperates with transverse moving component 1 to form XY cross coarse adjustment structure, realizing large-range servo coarse alignment of mounting plate 26 and the optical path structure above it in any plane position.

[0037] The light guide chamber 3 is fixedly installed on the side wall of the mounting plate 26. The side wall of the light source component 4 is fixedly installed with a fixing plate 5. Both ends of the fixing plate 5 are fixedly installed on the side wall of the mounting plate 26. The two ends of the fixing plate 5 are locked to the side wall of the mounting plate 26, which can form a stable clamping and positioning for the light source component 4, preventing the light source component 4 from loosening or shifting due to equipment vibration or environmental deformation. At the same time, it makes the light source component 4, the light guide chamber 3 and the mounting plate 26 form a rigid whole, and synchronously complete the two-dimensional position movement with the coarse adjustment device, keeping the light output axis of the light source coaxially aligned with the light path of the light guide chamber 3.

[0038] The pitch optical path adjustment component 8 is rotatably installed in the light guide chamber 3. The pitch optical path adjustment component 8 includes a reflector and a rotating mechanism 83. The two ends of the reflector are respectively installed with the rotating mechanism 83. The reflector is responsible for receiving the vertically emitted beam of the light source and completing the optical path turning and pitch angle adjustment. The pitch optical path adjustment component 8 is rotatably arranged in the internal cavity of the light guide chamber 3, forming a sealed protection with the light guide chamber 3. The rotating mechanism 83 provides rotation support, power transmission and rotation limit for the reflector, so that the rotating mechanism 83 drives the reflector to rotate slightly, thereby completing the optical path angle adjustment and deviation compensation of the quantum beam pitch direction.

[0039] Specifically, the reflector includes a rotating frame 81 and a reflector 82. The reflector 82 is installed in the rotating frame 81, which is tilted in the cavity of the light guide chamber 3. The tilt angle matches the vertical light output direction of the light source 4, so that the vertically upward quantum beam can be incident perpendicularly on the mirror surface of the reflector 82. The vertical beam is converted into a horizontal beam output by the mirror reflection effect of the reflector 82. At the same time, the rotating frame 81 can rotate synchronously with the rotating mechanism 83, which drives the reflector 82 to change the tilt angle, thereby realizing the fine adjustment of the pitch angle of the output horizontal beam.

[0040] The rotating mechanism 83 includes a gear ring 832 and a main shaft 833. The main shaft 833 is fixed at the center of both ends of the rotating frame 81. A bushing 834 is integrally formed in the side wall interlayer of the light guide chamber 3. The main shaft 833 is rotatably connected in the bushing 834 to provide centering for the rotating frame 81 and the reflector 82 and ensure coaxiality of rotation. Fixed columns 831 are fixedly connected to both sides of the rotating frame 81. The fixed columns 831 are fixedly installed on one side of the gear ring 832 so that the gear ring 832 can drive the rotating frame 81 to rotate synchronously. Positioning gears 837 are meshed and connected to both sides of the gear ring 832. The center of the positioning gears 837 is rotatably connected in the side wall interlayer of the light guide chamber 3 through a shaft. A drive rod 838 is fixedly installed on the shaft of one of the positioning gears 837. A drive gear 839 is keyed to the end of the drive rod 838.

[0041] External power is input through drive gear 839, which drives the corresponding positioning gear 837 to rotate through drive rod 838. Then, through meshing transmission, the gear ring 832 rotates as a whole, which finally drives the rotating frame 81 and the reflector 82 to swing slightly around the main shaft 833, so as to achieve precise adjustment of the pitch angle of the quantum optical path.

[0042] Furthermore, a limiting ring 835 is integrally formed on the outer side of the gear ring 832, and a limiting groove 836 is provided in the interlayer of the side wall of the light guide chamber 3. The limiting ring 835 is rotatably connected in the limiting groove 836. The circumferential stroke of the limiting ring 835 is limited by the annular space of the limiting groove 836. As a preferred embodiment, a damping bearing is installed in the limiting groove 836. The limiting ring 835 is fixed to the inner ring of the damping bearing, and the outer ring of the damping bearing is fixed in the limiting groove 836. By utilizing the friction damping characteristics of the damping bearing, the rotational resistance of the gear ring 832 is increased, so that the reflector 82 can achieve mechanical self-locking after being adjusted to any pitch angle, effectively resisting the lens self-deflection caused by equipment vibration and environmental temperature deformation.

[0043] Example 2, refer to Figure 4 , Figures 7-8This is the second embodiment of the present invention, which is based on the previous embodiment. The guide chamber 6 is installed at the light outlet of the light guide chamber 3 to receive the horizontal quantum beam after reflection and deflection. A lens module 7 is installed at the light outlet of the guide chamber 6. The lens module 7 uses the existing lens optics principle to collimate and shape the horizontal beam, correct the beam divergence and transmission loss, and improve the transmission quality of the quantum beam. The working principle of the lens module 7 is existing technology and can be clearly understood by those skilled in the art, so it will not be described in detail here. The horizontal light path adjustment component 9 is rotatably installed in the guide chamber 6. The horizontal light path adjustment component 9 includes a dimming element and a driving mechanism 94. The end of the dimming element is fixedly installed with the driving end of the driving mechanism 94. The dimming element is responsible for the secondary angle fine adjustment of the horizontal beam. The driving mechanism 94 provides transmission and angle locking for the dimming element, forming a rear horizontal light path fine adjustment compensation structure.

[0044] Specifically, the dimming component includes a rotating ring 91 and a parallel glass plate 92. The parallel glass plate 92 is installed in the rotating ring 91. The top and bottom ends of the rotating ring 91 are fixedly connected to a rotating shaft 93. The rotating shaft 93 is rotatably connected in the guide chamber 6, providing centering rotation for the rotating ring 91 and the parallel glass plate 92. The horizontal quantum beam is transmitted straight through the parallel glass plate 92. When the drive mechanism 94 drives the rotating shaft 93 to rotate the rotating ring 91 slightly, the parallel glass plate 92 synchronously changes its tilt angle. By utilizing the principle of glass refraction, the transmitted beam produces a slight horizontal sway and a vertical angle shift, realizing secondary angle fine-tuning compensation for the horizontal quantum light path.

[0045] The drive mechanism 94 includes a worm gear 941 and a worm 942. The worm gear 941 is keyed to the top of the rotating shaft 93, which can drive the rotating shaft 93 to rotate synchronously. The side wall of the worm gear 941 meshes with the worm 942, and the meshing of the worm gear 941 and the worm 942 forms a worm gear transmission pair. A transmission rod 943 is fixedly installed inside the worm 942. The side wall of the transmission rod 943 is rotatably mounted on the top surface of the guide chamber 6 through a support 944. The end of the transmission rod 943 is keyed to a driven bevel gear 945, which is connected to the drive gear 942. The sidewall meshing connection of bevel gear 946 enables a 90° reversal of the transmission direction. The interior of the driving bevel gear 946 is keyed to the transmission rod 948. The sidewall of the transmission rod 948 is rotatably mounted on the sidewall of the guide chamber 6 via the support 947. The sidewall of the transmission rod 948 is keyed to a worm gear 949, which serves as an external power input interface. The entire mechanism precisely controls the deflection angle of the parallel glass plate 92 through the transmission of the worm gear and bevel gear. After stopping, the worm gear self-locks the lens angle to prevent springback deviation after fine-tuning of the optical path.

[0046] Example 3, referring to Figure 8As shown, this is the third embodiment of the present invention. Based on the first two embodiments, the drive component 10 is selected to engage with the input end of the drive mechanism 94 or the input end of the rotation mechanism 83. By switching the position, it selectively engages with the input end of the rotation mechanism 83 and the input end of the drive mechanism 94 respectively, so that a single set of drive structures can provide power for pitch optical path adjustment and horizontal optical path fine adjustment in a time-division manner.

[0047] Specifically, the drive assembly 10 includes a linear module and a drive component. The drive component is mounted on the linear module and includes a servo motor 105. The output shaft of the servo motor 105 is keyed to a drive gear 106 and a worm gear 107, which can simultaneously output two different types of power. The servo motor 105 is driven by the linear module. The drive gear 106 is meshed with the input end of the rotary mechanism 83, and the worm gear 107 is meshed with the input end of the drive mechanism 94.

[0048] Relying on the linear displacement drive of the linear module, the servo motor 105 can be switched to different working positions. After switching to position one, the drive gear 106 meshes with the input end of the rotary mechanism 83 to provide power to the pitch optical path adjustment component 8. After switching to position two, the worm gear 107 meshes with the input end of the drive mechanism 94 to provide power to the horizontal optical path adjustment component 9, thereby realizing the alternating drive of the two optical path adjustment mechanisms.

[0049] The linear module includes a guide frame 101. A servo motor 102 is fixedly mounted on the side wall of the guide frame 101. The output shaft of the servo motor 102 is fixedly mounted to a lead screw 103 via a coupling. The lead screw 103 is rotatably mounted inside the guide frame 101 via a bearing. A nut slide 104 is threadedly connected to the side wall of the lead screw 103. A servo motor 105 is fixedly mounted on the top surface of the nut slide 104. A support frame 108 is fixedly mounted on one side of the bottom surface of the guide frame 101. The inner side of the support frame 108 is mounted on the side wall of the guide chamber 6, and the top surface of the support frame 108 is rotatably mounted to the bottom end of the transmission rod 948 via a bearing seat. A support frame 109 is fixedly mounted on the other side of the bottom surface of the guide frame 101. The inner side of the support frame 109 is mounted on the side wall of the light guide chamber 3.

[0050] Servo motor 3 102 provides linear motion power. Servo motor 3 102 drives lead screw 103 to rotate through coupling. The rotation of lead screw 103 drives the nut slide 104 with external thread to slide linearly back and forth. The nut slide 104 carries servo motor 4 105 to realize overall position switching. Support frame 1 108 and support frame 2 109 are respectively set on both sides of the bottom surface of guide frame 101, which are respectively attached and fixed to the side wall of guide chamber 6 and light guide chamber 3 to realize the fixation of drive component 10 with light guide chamber 3 and guide chamber 6. At the same time, the top surface of support frame 1 108 provides rotational support for the bottom end of transmission rod 2 948 through bearing seat, improving the transmission rotation accuracy of drive mechanism 94 and ensuring accurate and error-free power meshing.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
