[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0063] See Figure 2 , in an embodiment, the Herriott cell mirror group includes: a main reflection device 1 and a secondary reflection device 2, which are used to be installed in the gas cell cavity 3 after being debugged respectively; the main reflection device 1 includes: a main mirror adjustment seat 11 and a main reflecting mirror 12 and a small reflecting mirror 13 installed on the main mirror adjustment seat 11; the secondary reflection device 2 includes: a secondary mirror adjustment seat 21 and a secondary reflecting mirror 22 installed on the secondary mirror adjustment seat 21; the small reflecting mirror 13 is used to reflect the incident light onto the secondary reflecting mirror 22, and after the incident light is reflected multiple times between the secondary reflecting mirror 22 and the main reflecting mirror 12, it finally exits through the small reflecting mirror 13.

[0064] In this embodiment, the primary reflector 12 and the secondary reflector 22 may both be concave mirrors, and the small reflector 13 may be a plane mirror. Figure 1 The incident light is incident on the small reflector 13 , and the small reflector 13 reflects the incident light to the secondary reflector 22 . Then, the laser is reflected multiple times between the secondary reflector 22 and the main reflector 12 , and finally emitted through the small reflector 13 .

[0065] It should be noted that the curvatures of the primary reflector 12 and the secondary reflector 22 and the installation position of the small reflector 13 on the primary reflector 12 can be obtained through software simulation, which is a prior art and will not be described in detail here.

[0066] See also Figures 3 to 5 The primary mirror adjustment seat 11 and the secondary mirror adjustment seat 21 both include: a reflector fixing seat 111, used to fix the primary reflector 12 or the secondary reflector 22; a vertical bracket 112; the reflector fixing seat 111 is fixed on the vertical bracket 112 by a plurality of first adjusting screws 41; and a base 113, used to be fixed in the gas pool cavity 3; the vertical bracket 112 is fixed on the base 113 by a plurality of second adjusting screws 42; the primary mirror adjustment seat 11 also includes: a small mirror fixing seat 114 for fixing the small reflector 13; the small mirror fixing seat 114 is fixed on the reflector fixing seat 111 by a plurality of third adjusting screws 43; the small reflector 13 is passed through the small mirror mounting hole 121 on the primary reflector 12.

[0067] In this embodiment, the secondary mirror adjustment seat 21 may only lack the small mirror fixing seat 114 compared to the primary mirror adjustment seat 11 , and the rest of the structure may be the same as that of the primary mirror adjustment seat 11 .

[0068] See also Figure 6 and Figure 7 The side surfaces of the primary reflector 12 and the secondary reflector 22 each include at least one plane 122 ; the plane 122 is used for positioning when the primary reflector 12 or the secondary reflector 22 is installed on the reflector fixing seat 111 .

[0069] Optionally, a plane 122 may be provided on both side surfaces of the primary reflector 12 and the secondary reflector 22; an arc-shaped reflector mounting groove 1111 may be provided on the reflector fixing seat 111 for matching the arc-shaped side surfaces of the primary reflector 12 and the secondary reflector 22, and the primary reflector 12 and the secondary reflector 22 may be bonded in the reflector mounting groove 1111 by adhesive.

[0070] Specifically, during the installation process of the primary mirror 12 and the secondary mirror 22, the mirror fixing seat 111 can be first placed in a jig, and glue can be applied to the mirror installation groove 111. There are two guiding walls on the jig for guiding the plane 122. When the primary mirror 12 and the secondary mirror 22 are inserted into the mirror installation groove 1111, the installation angles of the primary mirror 12 and the secondary mirror 22 can be accurately defined due to the limitation of the plane 122 by the two guiding walls.

[0071] Furthermore, the mirror fixing seat 111 includes: a first installation surface 111a and a second installation surface 111b arranged oppositely; a mirror installation groove 1111 and a small mirror fixing seat installation hole 1112 are provided on the first installation surface 111a; a mirror fixing seat installation hole 1113 for installing the mirror fixing seat 111 on the vertical bracket 112 is provided on the second installation surface 111b.

[0072] Furthermore, a number of first through holes 1121 that are clearance - fitted with the first adjusting screw 41 are provided on the vertical bracket 112; after the first adjusting screw 41 passes through the first through hole 1121, it is fixedly connected to the corresponding mirror fixing seat installation hole 1113.

[0073] See Figure 8 and Fig. 9 Specifically, when fixing the mirror fixing seat 111 to the vertical bracket 112, the mirror fixing seat installation hole 1113 on the mirror fixing seat 111 can be aligned with the first through hole 1121, and then the first adjusting screw 41 is passed through the first through hole 1121 and screwed into the mirror fixing seat installation hole 1113, thereby fixing the mirror fixing seat 111 to the vertical bracket 112. Since the first adjusting screw 41 is clearance - fitted with the first through hole 1121, the pitching angle and the up - and - down position of the mirror fixing seat 111, that is, the pitching angle and the up - and - down position of the primary mirror 12 and the secondary mirror 22, can be adjusted by adjusting the position of the first adjusting screw 41 in the first through hole 1121. After the adjustment is completed, the first adjusting screw 41 can be tightened.

[0074] Furthermore, a number of third through holes 1141 that are clearance - fitted with the third adjusting screw 43 are provided on the small mirror fixing seat 114; after the third adjusting screw 43 passes through the third through hole 1141, it is fixedly connected to the corresponding small mirror fixing seat installation hole 1112.

[0075] See Figure 8 and Fig. 9Specifically, when fixing the small mirror fixing seat 114 to the reflector fixing seat 111, the small reflector 13 can be first inserted into the small mirror mounting hole 121, and then the third through hole 1141 is aligned with the small mirror fixing seat mounting hole 1112, and the third adjusting screw 43 is passed through the third through hole 1141 and then screwed into the small mirror fixing seat mounting hole 1112, thereby completing the fixing. Since the third adjusting screw 43 and the third through hole 1141 are clearance-matched, the position of the third adjusting screw 43 in the third through hole 1141 can be adjusted, thereby adjusting the front-rear position of the small reflector 13 in the small mirror mounting hole 121.

[0076] Furthermore, the bottom of the vertical bracket 112 is provided with a plurality of second through holes 1122 that are clearance-matched with the second adjusting screw 42; the base 113 is provided with a plurality of bracket mounting holes 1131 and a positioning column 1135 for positioning the vertical bracket 112; the second adjusting screw 42 passes through the second through hole 1122 and is fixedly connected with the corresponding bracket mounting hole 1131.

[0077] See also Fig.10 Specifically, when fixing the vertical bracket 112 to the base 113, the second through hole 1122 can be aligned with the bracket mounting hole 1131, and the side of the vertical bracket 112 can be ensured to be tightly against the positioning column 1135, and then the second adjusting screw 42 is passed through the second through hole 1122 and screwed into the bracket mounting hole 1131 to complete the fixing. Since the second adjusting screw 42 and the second through hole 1122 are clearance-matched, the left-right deflection angle and the front-back and left-right positions of the vertical bracket 112 can be adjusted on the horizontal plane by adjusting the position of the second adjusting screw 42 in the second through hole 1122, that is, the horizontal positions of the primary reflector 12 and the secondary reflector 22 can be adjusted.

[0078] Furthermore, the base 113 is also provided with: a plurality of pin holes 1132 for cooperation with the positioning pins 1133 in the gas pool cavity 3; and a base fixing hole 1134 for passing the fourth screw 44 to fix the base 113 on the gas pool cavity 3.

[0079] See also Fig.11 Specifically, when fixing the base 113 to the gas pool cavity 3, the pin hole 1132 can be aligned with the positioning pin 1133 and inserted to position the base 113 at a preset position on the gas pool cavity 3, and then the fourth screw 44 is passed through the base fixing hole 1134 and screwed into the mounting hole on the gas pool cavity 3 to fix the base 113 to the gas pool cavity 3.

[0080] It should be noted that the gas pool cavity 3 in the drawings may be a part of the pool wall of the Herriot pool, or may be a mounting seat in the pool.

[0081] In this embodiment, the Herriott pool reflector assembly uses the clearance between the screws and the fixing through holes to adjust the pitch, height and horizontal deflection angle of the primary reflector 12 and the secondary reflector 22, and the screws are used to fix them after the adjustment is completed, thereby avoiding the possibility of increasing deformation due to the spring adjustment in the prior art. The primary reflector 1 and the secondary reflector 2 can be adjusted separately, and can be put into storage for standby after the adjustment is completed. When they need to be assembled into the Herriott pool, the adjusted primary reflector 1 and the secondary reflector 2 can be installed in the corresponding preset positions, and no further adjustment is required during installation, thereby improving production efficiency.

[0082] In some application scenarios, the main reflector 1 and the secondary reflector 2 can be debugged according to the working optical path design principle of the Herriott cell reflector group, for example, the detection optical path is designed by simulating the working optical path, and then a detection platform is built for detection. The main reflector 1 and the secondary reflector 2 can be debugged separately, and the installation positions of the main reflector 12, the small reflector 13, and the secondary reflector 22 are debugged respectively, so that their reflection optical paths meet the working requirements.

[0083] Specifically, based on the above embodiments, an embodiment of the present application provides a Herriott cell reflector group debugging system, including: a platform 100, and a position to be detected 101, a first detection optical path 102 and a second detection pipeline 103 arranged on the platform; the position to be detected 101 is used to install the main reflection device 1 or the secondary reflection device 2; the first detection optical path 102 is used to debug the installation angles of the main reflection device 1 and the main reflection mirror 12 and the secondary reflection mirror 22 of the secondary reflection device 2; and the second detection pipeline 103 is used to debug the installation angle of the small reflection mirror 13 of the main reflection device 1.

[0084] For details, see Fig.12 When debugging the primary reflector 12 or the secondary reflector 22, a light path with two reflections is designed, that is, if the incident light is reflected twice at the center point on the primary reflector 12 or the secondary reflector 22 and then observed at a preset position, it is qualified.

[0085] Specifically, the first detection optical path 102 includes a laser, small holes 1-1 to 9-1, and an observation point. The spot of the indicator laser output by the laser can be 1 mm, and the apertures of all small holes can also be designed to be 1 mm, and the heights of the small holes are all the same.

[0086] The indicator laser emitted by the laser is collimated through the small holes 1-1 and 2-1 and then incident on the center point of the main reflector 12 or the secondary reflector 22. The degrees of freedom (up and down, pitch, horizontal, etc.) of the main reflector 12 or the secondary reflector 22 are adjusted so that the light passes through the small holes 3-1 and 4-1 and then passes through a reflector. The reflector is adjusted so that the light passes through the small holes 5-1 and then enters another reflector. The reflector is adjusted so that the light passes through the small holes 6-1 and 7-1 and then enters the main reflector 12 or the secondary reflector 22 again. If the main reflector 12 or the secondary reflector 22 is adjusted to an ideal position, the reflected light will pass through the small holes 8-1 and 9-1 and then reach the observation point, where a photosensitive film can be placed. If the laser is observed at the observation point, the debugging is completed, and the small reflector 13 is debugged.

[0087] In one application scenario, see Fig.13 and Fig.14 The plane of the small reflector 13 is required to be perpendicular to the horizontal plane, but there is a certain angle between the input light and the horizontal plane, so the reflected light also has a certain angle with the horizontal plane. The heights of the small holes A, B, C, and D are designed to be inconsistent. First, adjust the indicating laser to pass through small holes A and B. At this time, the indicating laser degree of freedom is locked. Adjust the pitch of the small reflector 13 so that the reflected light passes through small holes C and D and reaches the observation point. Similarly, if light is observed at the observation point, it means that the small round mirror is adjusted in place, and the side adjustment screws can be tightened.

[0088] On the basis of the above-mentioned embodiments, the present embodiment provides a method for installing the Herriott pool reflector group as described above, comprising: installing a main reflector 12 and a small reflector 13 on a main mirror adjustment seat 11 to form a main reflector 1; installing a secondary reflector 22 on a secondary mirror adjustment seat 21 to form a secondary reflector 2; debugging the installation angles of the main reflector 12 and the small reflector 13 of the main reflector 1, and after the debugging is completed, installing the main reflector 1 at a preset position in the gas pool cavity 3; debugging the installation angle of the secondary reflector 22 of the secondary reflector 2, and after the debugging is completed, installing the secondary reflector 2 at a preset position in the gas pool cavity 3.

[0089] In one application scenario, the secondary reflector has the same structure as the primary reflector, the only difference being that there is no mounting hole for the small reflector. The remaining mounting parts can be the same as those for the primary reflector. During installation and debugging, the installation and debugging techniques are exactly the same as those for the primary reflector, omitting the steps for the small reflector. After debugging is completed, loosen the screws fixing it to the platform and it can be put into storage for use.

[0090] In summary, the Herriott cell reflector assembly of the present invention is designed with a precise adjustment tool, so that the complex optical path debugging process is simplified and the production efficiency can be improved in mass production; the split structure of the primary mirror side and the secondary mirror side facilitates disassembly, assembly and maintenance; the lens sticking positioning tool effectively solves the parallelism problem between the bracket and the lens; the pin solves the problem of repeated positioning, so that the reflector adjusted on the tool can be conveniently transplanted into the cavity.

[0091] The various devices selected in this application (components whose specific structures are not described) are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
