[0024] Please see Figure 1-4 This utility model provides a technical solution: a measuring device for the light deflection angle of a graphene terahertz laser source, including a mounting base 1, a display body 2 for displaying the light deflection angle on one side of the mounting base 1, and a measuring mechanism for the light deflection angle of the graphene terahertz laser source on the mounting base 1, the measuring mechanism including:

[0027] In a preferred embodiment, the threaded assembly includes a screw 301 rotatably connected inside the slide groove 3, a slider 302 slidably connected to the inner wall of the slide groove 3, and a threaded connection between the slider 302 and the screw 301. A pair of guide rods 303 are fixed to the inner end face of the slide groove 3, and the guide rods 303 are slidably connected to the slider 302. When adjusting the position of the laser source, the screw 301 is rotated, and the slider 302 slides along the guide rods 303 inside the slide groove 3, driving the mounting base 4 and the laser source emitting body 404 to translate. After it is in place, the first bolt 601 is rotated to press the first rubber block 602 against the surface of the mounting base 1, thereby achieving the positioning and locking of the slider 302. The model of the laser source emitting body 404 is THz-QCL.

[0028] In a preferred embodiment, the detachable component includes a positioning groove 401 on the front and rear side walls of the mounting base 4, into which a positioning rod 402 is inserted. A mounting plate 403 is fixedly connected to the upper end of the positioning rod 402. Support shafts 5 are provided on the left and right side walls of the mounting base 4. A connecting block 501 is fixed to the outer wall of the support shaft 5. A locking bracket 502 is fixed to the upper end of the connecting block 501.

One end of the locking bracket 504 is in contact with the upper surface of the locking block 505. The locking bracket 504 and the locking block 505 are connected by a threaded bolt.

[0029] Specifically, when installing the laser source emitting body 404, the mounting plate 403 is placed on the upper surface of the mounting base 4, and the positioning rod 402 is inserted into the positioning groove 401 to achieve initial positioning. The support shaft 5 is rotated to drive the connecting block 501 and the locking bracket 502 to rotate, so that the locking bracket 502 is locked into the groove 503 on the edge of the mounting plate 403. Then, the locking bracket 504 and the locking block 505 are fixed by the threaded bolt, thus completing the detachable fixing of the mounting plate 403 and the laser source emitting body 404.

[0031] When measuring the laser deflection angle, the laser beam irradiates the laser receiving plate 706 to form a light spot. The movable disk 702 is rotated, which causes the mounting block 704, mounting rod 705 and laser receiving plate 706 to rotate around the mounting shaft 701 until the light spot is aligned with the reference point of the laser receiving plate 706. At this time, the pointer 703 on the edge of the movable disk 702 points to the corresponding scale on the angle scale 7, which is the deflection angle.

[0032] Furthermore, when fixing the angle, rotating the second bolt 708 causes the second rubber block 709 to press against the surface of the mounting base 1, and locking the position of the mounting shaft 701 and the movable plate 702 by the second positioning bracket 707.

[0033] The insertion structure between the mounting rod 705 and the mounting block 704 allows the mounting rod 705 to slide inside the mounting block 704 and be tightened by bolts. This facilitates adjustment of the height of the laser receiving plate 706, adapts to the output height of different laser sources, and improves the versatility of the device.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] In the measuring device for the light deflection angle of the graphene terahertz laser source, when installing the laser source emitting body 404, the mounting plate 403 is placed on the upper end face of the mounting base 4, and the positioning rod 402 is inserted into the positioning groove 401 to achieve initial positioning. The support shaft 5 is rotated to drive the connecting block 501 and the locking bracket 502 to rotate, so that the locking bracket 502 is locked into the groove 503 on the edge of the mounting plate 403. Then, the locking bracket 504 is fixed to the locking block 505 by the threaded bolt, thus completing the detachable fixing of the mounting plate 403 and the laser source emitting body 404.

[0036] When adjusting the position of the laser source, rotate the screw 301, and the slider 302 slides along the guide rod 303 in the slide groove 3, which drives the mounting base 4 and the laser source emitting body 404 to move in place. After it is in place, rotate the first bolt 601 to make the first rubber block 602 press against the surface of the mounting base 1, thereby realizing the positioning and locking of the slider 302.

[0037] When measuring the laser deflection angle, the laser beam irradiates the laser receiving plate 706 to form a light spot. The movable disk 702 is rotated, causing the mounting block 704, mounting rod 705, and laser receiving plate 706 to rotate around the mounting shaft 701 until the light spot is aligned with the reference point of the laser receiving plate 706. At this time, the pointer 703 on the edge of the movable disk 702 points to the corresponding scale on the angle scale 7, which is the deflection angle. The insertion structure between the mounting rod 705 and the mounting block 704 allows the mounting rod 705 to slide inside the mounting block 704 and be locked by bolts, which facilitates the adjustment of the height of the laser receiving plate 706 to adapt to the output height of different laser sources and improve the versatility of the device. When fixing the angle, the second bolt 708 is rotated to make the second rubber block 709 press against the surface of the mounting base 1, and the position of the mounting shaft 701 and the movable disk 702 is locked by the second positioning bracket 707.
