Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for Michelson interferometry experiments, specifically a double-layer moving stage for Michelson interferometry experiments. Background Technology

[0002] The Michelson interferometer is the most common type of optical interferometer. Its principle is that an incident beam of light is split into two beams by a beam splitter and then reflected back by corresponding plane mirrors. Because the two beams of light have the same frequency, the same direction of vibration, and a constant phase difference (i.e., satisfy the interference condition), they can interfere. The different optical paths of the two beams of light in the interference can be achieved by adjusting the length of the interference arm and changing the refractive index of the medium, thereby forming different interference patterns.

[0003] According to the patent application disclosed on the Internet, a precision double-layer moving stage for a Michelson interferometry experiment (authorization announcement number: CN217130823 U) is described as follows: "This utility model discloses a precision double-layer moving stage for a Michelson interferometry experiment, including a base, a coarse adjustment moving stage, a coarse adjustment mechanism, a fine adjustment moving stage, and a fine adjustment mechanism. The coarse adjustment moving stage is slidably connected to the upper surface of the base, and the coarse adjustment mechanism is used to drive the coarse adjustment moving stage to move left and right on the base. The fine adjustment moving stage is slidably connected to the upper surface of the coarse adjustment moving stage, and the fine adjustment mechanism is used to drive the fine adjustment moving stage to move left and right on the coarse adjustment moving stage. The beneficial effect of this utility model is that, during the experiment, the moving mirror assembly can be installed on the fine adjustment moving stage. The coarse adjustment moving stage can be driven to move quickly on the base by the coarse adjustment mechanism, which can meet the need for large stroke adjustment. The fine adjustment moving stage can be driven to make fine adjustments on the coarse adjustment moving stage by the fine adjustment mechanism, thereby meeting the need for high-precision adjustment. The dual adjustment can achieve fast and accurate adjustment."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, rotating the first cover can drive the first screw to rotate synchronously. At this time, the first screw can move left and right in the first adjusting cylinder, thereby pushing the coarse adjustment stage to move left and right on the base, and then the fine adjustment stage and the moving mirror move synchronously. In actual use, because the mounting hole position of the fine adjustment stage of this device is fixed, it is not suitable for installation and use of moving mirrors of different sizes. At the same time, the mounting angle of the stage is fixed, which makes it impossible to meet the adjustment needs of different experiments. Therefore, it is necessary to improve the device to a double-layer moving stage for Michelson interferometry experiments to solve the above problems. Utility Model Content

[0029] Example 1:

[0030] To address the problem that existing technologies with fixed mounting holes for fine-tuning stages are incompatible with different sized mirrors, this embodiment provides a double-layered stage for Michelson interferometry experiments. Please refer to [link to relevant documentation]. Figures 1-5 This utility model provides a technical solution: a double-layer moving stage for Michelson interferometry experiments, including a mounting plate 1 and a support plate 2, a mounting disk 3 rotatably connected to the top of the support plate 2, an adjustment mounting mechanism 4 provided on the top of the support plate 2, and a linear adjustment mechanism 5 provided on the top of the mounting plate 1;

A connecting rod 414 is rotatably connected to the top of the connecting column 413. This facilitates the adjustment and limiting of the angle of the mounting plate 3, thereby meeting the different experimental needs of adjusting the angle of the Michelson interferometer experimental moving mirror assembly.

[0033] Furthermore, the connecting rod 414 is rotatably connected to the mounting plate 3, the movable block 416 is threadedly connected to the bidirectional threaded rod 412, and the movable block 416 is slidably connected to the connecting table 411, which facilitates a more stable operation.

[0034] Furthermore, the mounting component 42 includes a limiting frame 421, which is fixedly connected inside the mounting plate 3. A slider 422 is slidably connected inside the limiting frame 421.

[0035] Furthermore, the slide plate 426 is slidably connected to the slide rod 424, and the limit frame 421 and the corresponding position of the locking block 427 are provided with grooves, and the locking block 427 is inserted into the groove, which makes the installation process more stable.

[0036] Example 2:

[0037] Based on Embodiment 1, the fixed installation angle of the moving stage in the prior art makes it impossible to adjust it to meet different experimental needs. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figures 6-7 Furthermore, in conjunction with Embodiment 1, the linear adjustment mechanism 5 includes an adjustment platform 51, which is fixedly connected to the top of the mounting plate 1. A connecting box 52 is fixedly connected to the right side of the adjustment platform 51. A worm gear 53 is rotatably connected inside the connecting box 52. A second threaded rod 55 is rotatably connected inside the adjustment platform 51. A worm wheel 56 is fixedly connected to the outside of the second threaded rod 55. A second limiting rod 57 is fixedly connected inside the adjustment platform 51. A connecting block 54 is slidably connected to the outside of the second limiting rod 57, which facilitates the adjustment of the horizontal position of the support plate 2, thereby meeting different adjustment needs.

[0038] Furthermore, the worm 53 meshes with the worm wheel 56, the connecting block 54 is threadedly connected to the second threaded rod 55, the adjusting table 51 and the connecting block 54 are respectively provided with grooves, and the connecting block 54 is slidably connected inside the groove. The connecting block 54 is fixedly connected to the support plate 2, which makes the adjustment process more stable.

[0039] In actual operation, when this device is used, the operator first installs and limits the mounting plate 1 to the designated position using the device with the locking bolts. After installation, the operator adjusts it according to the model of the Michelson interferometer movable mirror assembly. The operator pulls the sliding plate 426, and the movement of the sliding plate 426, in conjunction with the spring 425, causes the locking block 427 to move. The movement of the slider 422 causes the mounting block 423 to move until it reaches the designated position. Then, the sliding plate 426 is released. Under the action of the spring 425, the locking block 427 is limited between itself and the limiting frame 421. Finally, the locking bolts are used to complete the connection between the mounting block 423 and the Michelson interferometer movable mirror. After the components are installed, the staff adjusts the angle of the Michelson interferometer moving mirror component according to the experimental requirements. The staff rotates the bidirectional threaded rod 412. The rotation of the bidirectional threaded rod 412, in conjunction with the first limit rod 415, causes the movable block 416 to move, thereby causing the connecting column 413 to move. In conjunction with the connecting rod 414, the mounting plate 3 rotates on top of the support plate 2. After the adjustment is completed, the staff rotates the worm gear 53. The rotation of the worm gear 53, in conjunction with the worm wheel 56, causes the second threaded rod 55 to rotate inside the adjusting table 51. In conjunction with the second limit rod 57, the connecting block 54 slides inside the adjusting table 51, thereby adjusting the horizontal position of the support plate 2.
