[0056] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0057] It should be noted that holographic sights are commonly used in weapons such as submachine guns, rifles, and shotguns, offering advantages such as rapid and accurate aiming. The holographic matching filter is one of the components in the optical system of a holographic sight, and its optical performance has a direct impact on the overall performance of the holographic sight. Therefore, during the mass production of holographic sights, it is usually necessary to perform optical performance testing on each holographic matching filter.

[0058] When performing optical performance testing, the holographic matched filter needs to be placed between the laser source and the target plate. The tester determines whether the holographic matched filter is qualified based on the imaging of the laser light passing through the holographic matched filter on the target plate.

[0059] However, the holographic matched filter testing process in related technologies involves a large amount of manual operation. The testing personnel need to hold the filter to be tested by hand to place it between the laser source and the target plate, and adjust the position of the filter between the laser source and the target plate. This not only results in low testing efficiency, but also easily causes the holographic matched filter to become contaminated, which is not conducive to improving the manufacturing efficiency of holographic sights.

[0060] In view of this, such as Figures 1 to 14 As shown, a detection device for a holographic matched filter is provided according to a first aspect of the present disclosure, comprising: a base 100; a target plate assembly 200 disposed on the base 100, the target plate assembly 200 having a target surface 201; a laser emitting assembly 300 disposed on the base 100, the laser emitting assembly 300 being used to emit a detection laser beam toward the target surface 201; and a support assembly 400 disposed on the base 100, the support assembly 400 being arranged between the target plate assembly 200 and the laser emitting assembly 301, the support assembly 400 having a limiting slot 401 for inserting a holographic matched filter to be detected, so that the holographic matched filter to be detected is located on the propagation path of the detection laser beam.

[0061] The detection device for a holographic matched filter provided in this embodiment includes the aforementioned base 100, target plate assembly 200, laser emitting assembly 300, and support assembly 400. In practical applications, the base 100 can serve as a carrier for other components of the aforementioned detection device, providing structural support. Correspondingly, the target plate assembly 200, laser emitting assembly 300, and support assembly 400 are all mounted on the base 100, thereby ensuring the structural stability of the target plate assembly 200, laser emitting assembly 300, and support assembly 400 during the detection process. The target surface 201 of the target plate assembly 200 is arranged opposite to the emitting end of the laser emitting assembly 300, and the laser emitting assembly 300 is used to emit a detection laser beam towards the target surface 201. The support assembly... The support assembly 400 is disposed on the base 100 and located between the target plate and the laser emitting assembly 300. The support assembly 400 has a limiting slot 401 for accommodating and constraining the position of the holographic matched filter to be tested. The notch of the limiting slot 401 is suitable for the holographic matched filter to be tested to pass through, thus facilitating the insertion or removal of the holographic matched filter by the testing personnel. When the holographic matched filter to be tested is inserted into the limiting slot 401, it can be positioned on the propagation path of the aforementioned detection laser beam, thereby allowing the detection laser beam to pass through the holographic matched filter to be tested. The matched filter is projected onto the target surface 201. Correspondingly, the operator can judge the qualification status of the holographic matched filter to be tested by observing the imaging effect of the detection laser beam on the target surface 201. After the test is completed, the operator can remove the holographic matched filter from the limiting slot 401 to facilitate subsequent operations on the tested holographic matched filter. Based on this, the holographic matched filter testing device provided in this embodiment can use the base 100 to support the target plate assembly 200, the laser emitting assembly 300, and the bracket assembly 400, and constrain the relative positions between the target plate assembly 200, the laser emitting assembly 300, and the bracket assembly 400. At the same time, the bracket assembly 400 can be used to accommodate and limit the holographic matched filter to be tested. Thus, during the testing of the holographic matched filter, the testing personnel do not need to hold and fix the holographic matched filter to be tested or adjust its position. The operation of inserting or removing the holographic matched filter from the limiting slot 401 is convenient. This can improve testing efficiency, reduce the risk of contamination of the holographic matched filter, and help improve the manufacturing efficiency of the holographic sight.

[0062] It should be noted that, Figure 1 The straight line segment L is used to schematically represent the detection laser beam.

[0063] It is understood that holographic matched filters are typically sheet-like structures. During the detection process, the detection laser beam can be directed towards one side of the thickness direction of the holographic matched filter to be detected, and projected onto the target surface 201 through the other side of the thickness direction of the holographic matched filter to be detected. Based on this, in practical applications, the shape of the aforementioned limiting slot 401 can be combined with the shape of the holographic matched filter to be detected, so that the limiting slot 401 is adapted to the holographic matched filter to be detected. The slot of the limiting slot 401 can be opened on the top of the support assembly 400. The thickness and width directions of the slot of the limiting slot 401 can be matched with the thickness and width directions of the holographic matched filter to be detected, respectively, and the depth direction of the limiting slot 401 can be matched with the height direction of the holographic matched filter to be detected. The slot thickness of the limiting slot 401 can be greater than or equal to the thickness of the holographic matched filter to be tested, and the slot width of the limiting slot 401 can be greater than or equal to the width of the holographic matched filter to be tested. The depth of the limiting slot 401 can be set in conjunction with the height of the holographic matched filter to be tested, so as to facilitate the insertion or removal of the holographic matched filter to be tested. The thickness direction of the slot of the limiting slot 401 can be arranged along the emission direction of the laser emitting component 300, so as to facilitate the detection of the laser beam being directed toward one side of the thickness direction of the holographic matched filter to be tested, and projected onto the target surface 201 through the other side of the thickness direction of the holographic matched filter to be tested. The side of the limiting slot 401 facing the laser emitting component 300 and the side facing the target surface 201 can both be hollowed out, so as to facilitate the detection of the laser beam passing through.

[0064] Understandably, in practical applications, the structural parameters of the target assembly 200, the laser emitting assembly 300, and the support assembly 400, as well as their positions on the base 100, can be specifically set so that the center of the emitting end of the laser emitting assembly 300, the center of the holographic matched filter to be tested, and the center of the target surface 201 are on the same plane, thereby helping to further ensure the detection effect.

[0065] It is understood that the detection device for the holographic matched filter provided in this embodiment can reduce manual operation in the detection process and correspondingly reduce the risk of the detection personnel directly looking at the detection laser beam, which is conducive to improving the safety of the detection process. For example, in practical applications, a reminder label can be affixed to a conspicuous position on the laser emitting component 300 to prompt the detection personnel to avoid the propagation path of the detection laser beam.

[0066] like Figure 1 and Figure 2 As shown, in some examples, the emission direction of the laser emitting assembly 300 is perpendicular to the target surface 201, and the positions of the target plate assembly 200, the laser emitting assembly 300, and the support assembly 400 in the emission direction can all be adjusted.

[0067] In this technical solution, by constraining the emission direction of the laser emitting component 300, it is convenient to compare the imaging of the detection laser beam directly projected onto the target surface 201 and projected onto the target surface 201 through the holographic matched filter to be tested. This allows for the determination of whether the holographic matched filter is qualified, which helps to further ensure the detection effect. By setting the positions of the target plate component 200, laser emitting component 300, and support component 400 in the emission direction to be adjustable, the structural flexibility of the aforementioned detection device can be improved. This makes it easy to change the relative positional relationship between the target plate component 200, laser emitting component 300, and support component 400 according to the parameter specifications of the holographic matched filter to be tested. This helps to improve the adaptability of the aforementioned detection device to the detection of holographic matched filters of different specifications, reduce the amount of detection equipment used in the detection process, and further improve the detection efficiency.

[0068] like Figures 1 to 8 As shown, in some examples, the target plate assembly 200 includes: a base plate 210 disposed at the top of the base 100, the base 100 having a first connecting hole 101, the base plate 210 having a first elongated hole 2101, the axial direction of the first elongated hole 2101 being parallel to the axial direction of the first connecting hole 101, and the length direction of the first elongated hole 2101 extending along the firing direction, the base plate 210 being adapted to move relative to the base 100 along the firing direction; a target plate body 220 disposed on the side of the base plate 210 away from the base 100, the target plate body 220 having a target surface 201; and a first fastener 230 detachably passing through the first connecting hole 101 and the first elongated hole 2101, the first fastener 230 being used to securely connect the base plate 210 and the base 100.

[0069] In this technical solution, the target plate assembly 200 may include the aforementioned base plate 210, target plate body 220, and first fastener 230. Based on the aforementioned configuration, the target plate assembly 200 can change the position of the base plate 210 and the target surface 201 in the firing direction by adjusting the relative positional relationship between the first connecting hole 101 and the first elongated hole 2101 along the aforementioned firing direction. Correspondingly, during the process of adjusting the position of the target plate assembly 200 in the firing direction, the aforementioned first fastener 230 can be in a disassembled state to release the positional constraint on the base plate 210. After the position of the base plate 210 is adjusted to the correct position, the aforementioned first fastener 230 can be inserted through the first elongated hole 2101 and the first connecting hole 101 to fasten the base plate 210 and the base 100, preventing the position of the base plate 210 from changing, thereby improving the positional stability of the base plate 210 and the target plate body 220 and ensuring the detection effect.

[0070] It is understood that the aforementioned first fastener 230 may include a first fastening bolt and a first fastening nut. The diameter of the aforementioned first connecting hole 101 is adapted to the diameter of the shank of the first fastening bolt, the width of the aforementioned first elongated hole 2101 is adapted to the diameter of the shank of the aforementioned first fastening bolt, and the length of the aforementioned first elongated hole 2101 is greater than the diameter of the shank of the aforementioned first fastening bolt. In practical applications, the shank of the first fastening bolt can pass through the first elongated hole 2101 and the first connecting hole 101, and the head of the first fastening bolt is located on the side of the base plate 210 away from the top of the base 100. The first fastening nut is threadedly connected to the shank of the first fastening bolt and is located on the side of the base 100 away from the base plate 210. For example, the specification of the aforementioned first fastening bolt may be M6×18.

[0071] It is understandable that, such as Figure 2 and Figure 3 As shown, the number of the aforementioned first connecting holes 101 can be multiple, and the multiple first connecting holes 101 can be divided into multiple groups. Each group includes at least two first connecting holes 101 arranged at intervals along the emission direction, and the multiple groups are arranged at intervals along a direction perpendicular to the emission direction. The number of the aforementioned first elongated oval holes 2101 can also be multiple, and the number of first elongated oval holes 2101 is the same as the number of groups of first connecting holes 101. Each first elongated oval hole 2101 corresponds to a group of first connecting holes 101, and each first elongated oval hole 2101 corresponds to a first fastener 230. Based on this, on the one hand, when multiple first fasteners 230 are provided on the base 100 and the base plate 210, the limiting effect on the base plate 210 can be improved; on the other hand, the position adjustment range of the target plate assembly 200 in the emission direction can also be expanded, which is beneficial for the aforementioned detection device to adapt to the detection operation of more specifications of holographic matched filters.

[0072] For example, the target plate body 220 can be screwed to the top of the base plate 210. The specifications, type, and number of screws connecting the target plate body 220 and the base plate 210 can be selected according to actual needs. For example, the screws connecting the target plate body 220 and the base plate 210 can be, but are not limited to, three M6×18 socket head cap screws. The precision class of the threaded holes for mounting screws on the target plate body 220 and the base plate 210 can be 7H.

[0073] For example, the base plate 210 and the target plate body 220 can be plate-shaped structures that are generally rectangular, and the four corners of the base plate 210 and the target plate body 220 can be chamfered.

[0074] For example, such as Figure 6 As shown, the target plate body 220 may be provided with weight-reducing holes to reduce the overall weight of the target plate body 220 and the target plate assembly 200, which is beneficial to improving the mobility of the target plate assembly 200.

[0075] It is understandable that the dimensions and surface roughness of the base plate 210 and the target plate body 220 can be set according to actual needs, and no further restrictions are imposed here.

[0076] like Figure 1 , Figure 2 and Figure 8 As shown, in some examples, the target plate assembly 200 further includes a stiffener 240 connected between the base plate 210 and the target plate body 220.

[0077] In this technical solution, the target plate assembly 200 may further include the aforementioned stiffening rib 240. Based on the aforementioned configuration, the stiffening rib 240 can enhance the connection reliability between the target plate body 220 and the base plate 210, improve the structural strength of the target plate assembly 200, and extend the service life of the target plate assembly 200.

[0078] For example, such as Figure 8 As shown, the stiffening plate 240 may have weight-reducing holes to lighten the overall weight of the stiffening plate 240 and the target plate assembly 200, thereby improving the mobility of the target plate assembly 200. The stiffening plate 240 may be a roughly triangular plate structure with chamfered edges at its three corners. The stiffening plate 240 can be screwed to the target plate body 220 and to the base plate 210. The specifications, types, and quantities of the aforementioned screws can be selected according to actual needs. For example, the stiffening plate 240 can be fastened to the base plate 210 and the target plate body 220 respectively using four M6×12 socket head cap screws. The number of stiffening plates 240 can be selected according to actual needs; for example, there may be two stiffening plates 240. The precision grade of the threaded holes on the stiffening plate 240 for mounting screws can be 7H.

[0079] Understandably, the dimensions and surface roughness of the rib plate 240 can be set according to actual needs, and no further restrictions are imposed here.

[0080] like Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, in some examples, the laser emitting assembly 300 includes: a first base plate 310 disposed at the top of a base 100, the base 100 having a second connecting hole 102, the first base plate 310 having a second elongated hole 3101, the axial direction of the second elongated hole 3101 being parallel to the axial direction of the second connecting hole 102, and the length direction of the second elongated hole 3101 extending along the emission direction, the first base plate 310 being adapted to move relative to the base 100 along the emission direction; a first vertical plate 320 disposed on the side of the first base plate 310 away from the base 100, the first vertical plate 320 having a mounting hole 3201; a second fastener 330 detachably passing through the second connecting hole 102 and the second elongated hole 3101, the second fastener 330 being used to securely connect the first base plate 310 and the base 100; and a laser collimating light source 340 passing through the mounting hole 3201, used to emit a detection laser beam along the emission direction.

[0081] In this technical solution, the laser emitting assembly 300 may include the aforementioned first base plate 310, first vertical plate 320, second fastener 330, and laser collimating light source 340. Based on the aforementioned configuration, the laser emitting assembly 300 can change the positions of the first base plate 310, first vertical plate 320, and laser collimating light source 340 in the emission direction by adjusting the relative positional relationship between the second connecting hole 102 and the second elongated hole 3101 along the aforementioned emission direction. Correspondingly, during the adjustment of the position of the laser emitting assembly 300 in the emission direction, the aforementioned second fastener 330 can be in a disassembled state to release the positional constraint on the first base plate 310. After the position of the first base plate 310 is adjusted to the correct position, the aforementioned second fastener 330 can be inserted through the second elongated hole 3101 and the second connecting hole 102 to fasten the first base plate 310 to the base 100, preventing the first base plate 310 from changing position, thereby improving the positional stability of the laser emitting assembly 300 and ensuring the detection effect.

[0082] It is understandable that by using a laser collimating source 340 to emit the aforementioned detection laser beam, the collimation of the detection laser beam can be improved, thereby ensuring the detection effect. For example, the laser collimating source 340 can be used to emit a red semiconductor laser with a wavelength of 650nm, the power of the aforementioned semiconductor laser is 5mW, and the beam diameter of the aforementioned semiconductor laser is 0.2mm.

[0083] It is understood that the aforementioned second fastener 330 may include a second fastening bolt and a second fastening nut. The diameter of the aforementioned second connecting hole 102 is adapted to the diameter of the shank of the second fastening bolt, the width of the aforementioned second elongated hole 3101 is adapted to the diameter of the shank of the aforementioned second fastening bolt, and the length of the aforementioned second elongated hole 3101 is greater than the diameter of the shank of the aforementioned second fastening bolt. In practical applications, the shank of the second fastening bolt can pass through the second elongated hole 3101 and the second connecting hole 102, and the head of the second fastening bolt is located on the side of the first base plate 310 away from the top of the base 100. The second fastening nut is threadedly connected to the shank of the second fastening bolt and is located on the side of the base 100 away from the second base plate 410. For example, the specification of the aforementioned second fastening bolt may be M6×18.

[0084] It is understandable that, such as Figure 2 and Figure 9 As shown, the number of the aforementioned second connecting holes 102 can be multiple, and the multiple second connecting holes 102 can be divided into multiple groups. Each group includes at least two second connecting holes 102 arranged at intervals along the emission direction, and the multiple groups are arranged at intervals along a direction perpendicular to the emission direction. The number of the aforementioned second elongated holes 3101 can also be multiple, and the number of second elongated holes 3101 is the same as the number of groups of second connecting holes 102. Each second elongated hole 3101 corresponds to a group of second connecting holes 102, and each second elongated hole 3101 corresponds to a second fastener 330. Based on this, on the one hand, when multiple second fasteners 330 are all provided on the base 100 and the second base plate 410, the limiting effect on the second base plate 410 can be improved; on the other hand, the position adjustment range of the laser emitting assembly 300 in the emission direction can also be expanded, which is beneficial for the aforementioned detection device to adapt to the detection operation of more specifications of holographic matched filters.

[0085] For example, the first vertical plate 320 can be screwed to the top of the first base plate 310. The specifications, type, and number of screws connecting the first vertical plate 320 and the first base plate 310 can be selected according to actual needs. For example, the screws connecting the first vertical plate 320 and the first base plate 310 can be, but are not limited to, four M6×18 socket head cap screws. The precision class of the threaded holes for mounting screws on the first vertical plate 320 and the first base plate 310 can be 7H. The number of the aforementioned first vertical plates 320 can be selected according to actual needs; for example, the number of first vertical plates 320 can be two.

[0086] For example, the first base plate 310 may be a generally rectangular plate structure, and the four corners of the first base plate 310 may be chamfered. The first vertical plate 320 may be a generally T-shaped plate structure, and the edges of the first vertical plate 320 may be chamfered.

[0087] For example, the parallelism of the two sides of the first base plate 310 in the thickness direction can be ensured by milling, and the axial direction of the mounting hole 3201 and the aforementioned launching direction can be parallel to the two sides of the first base plate 310 in the thickness direction.

[0088] For example, such as Figure 10 As shown, when there is a protruding structure on the outer peripheral wall of the laser collimating light source 340, a groove 3202 adapted to the shape of the aforementioned protruding structure can also be provided on the first vertical plate 320 to facilitate the laser collimating light source 340 to pass through and be positioned.

[0089] For example, such as Figure 10 As shown, the first vertical plate 320 may be provided with weight-reducing holes to reduce the overall weight of the first vertical plate 320 and the laser emitting component 300, which is beneficial to improving the mobility of the laser emitting component 300.

[0090] It is understandable that the dimensions and surface roughness of the first base plate 310 and the first vertical plate 320 can be set according to actual needs, and no further restrictions are imposed here.

[0091] like Figure 1 , Figure 2 and Figure 11 As shown, in some examples, the laser emitting assembly 300 further includes: a switch carrier plate 350 disposed on the first vertical plate 320, the switch carrier plate 350 having a control screw hole 3501, the control screw hole 3501 being arranged corresponding to the control end of the laser collimating light source 340; a control bolt 360 passing through the control screw hole 3501, the control bolt 360 being threadedly engaged with the control screw hole 3501, the head of the control bolt 360 being arranged away from the control end, and the shank of the control bolt 360 being adapted to move axially along the control screw hole 3501 to abut or separate from the control end; wherein, when the shank of the control bolt 360 abuts against the control end, the laser collimating light source 340 emits a detection laser beam; when the shank of the control bolt 360 separates from the control end, the laser collimating light source 340 is turned off.

[0092] In this technical solution, the laser emitting assembly 300 may further include the aforementioned switch carrier plate 350 and control bolt 360. Based on the aforementioned configuration, the laser emitting assembly 300 can utilize the control bolt 360 to control the operation of the laser collimating light source 340. Accordingly, in practical applications, the testing personnel can tighten or loosen the control bolt 360 to make its rod contact or disconnect from the control end of the laser collimating light source 340, thereby causing the laser collimating light source 340 to emit or stop emitting the detection laser beam. This further enhances the ease of use of the aforementioned testing device, reduces the operational difficulty for testing personnel, and provides further assurance for improved testing efficiency.

[0093] For example, the switch carrier plate 350 can be screwed to the top of the first vertical plate 320. The specifications, type, and number of screws connecting the first vertical plate 320 and the switch carrier plate 350 can be selected according to actual needs. For example, the screws connecting the first vertical plate 320 and the switch carrier plate 350 can be, but are not limited to, two M5×12 socket head cap screws. The precision class of the threaded holes for mounting screws on the first vertical plate 320 and the switch carrier plate 350 can be 7H.

[0094] For example, the switch carrier 350 may be a generally rectangular plate structure, and the four corners of the switch carrier 350 may be chamfered.

[0095] For example, the control bolt 360 can be a knurled small head screw with a specification of M5×16.

[0096] Understandably, the size and surface roughness of the switch carrier board 350 can be set according to actual needs, and no further restrictions are imposed here.

[0097] like Figure 1 As shown, in some examples, the laser emitting assembly 300 further includes a light source fastener 370, which is detachably disposed on the first vertical plate 320 for fastening the laser collimating light source 340 to the first vertical plate 320.

[0098] In this technical solution, the laser emitting assembly 300 may further include the aforementioned light source fastener 370. Based on the aforementioned configuration, the laser emitting assembly 300 can utilize the light source fastener 370 to improve the installation stability of the laser collimating light source 340 on the first vertical plate 320, which is beneficial for further ensuring detection effect and efficiency.

[0099] For example, the aforementioned light source fastener 370 may include two M5×10 slotted flat-end set screws. The outer peripheral wall of the laser collimating light source 340 may be formed with a positioning groove. The tip of the aforementioned slotted flat-end set screw may be inserted into the aforementioned positioning groove to achieve tight positioning of the laser collimating light source 340.

[0100] like Figure 1 , Figure 2 , Figures 12 to 14As shown, in some examples, the support assembly 400 includes: a second base plate 410 disposed at the top of the base 100, the base 100 having a third connecting hole 103, the second base plate 410 having a third elongated hole 4101, the axial direction of the third elongated hole 4101 being parallel to the axial direction of the third connecting hole 103, and the length direction of the third elongated hole 4101 extending along the emission direction, the second base plate 410 being adapted to move relative to the base 100 along the emission direction; a second vertical plate 420 disposed on the side of the second base plate 410 away from the base 100, the second vertical plate 420 having a limit slot 401; and a third fastener 430 detachably passing through the third connecting hole 103 and the third elongated hole 4101, the third fastener 430 being used to securely connect the second base plate 410 to the base 100.

[0101] In this technical solution, the support assembly 400 may include the aforementioned second base plate 410, second vertical plate 420, and third fastener 430. Based on the aforementioned configuration, the support assembly 400 can change the position of the second base plate 410 and the second vertical plate 420 in the emission direction by adjusting the relative positional relationship between the third connecting hole 103 and the third elongated hole 4101 along the aforementioned emission direction. Correspondingly, during the adjustment of the position of the support assembly 400 in the emission direction, the aforementioned third fastener 430 can be in a disassembled state to release the positional constraint on the second base plate 410. After the position of the second base plate 410 is adjusted to the correct position, the aforementioned third fastener 430 can pass through the third elongated hole 4101 and the third connecting hole 103 to fasten the second base plate 410 to the base 100, preventing the second base plate 410 from changing position, thereby improving the positional stability of the second base plate 410 and the second vertical plate 420 and ensuring the detection effect.

[0102] It is understood that the aforementioned third fastener 430 may include a third fastening bolt and a third fastening nut. The diameter of the aforementioned third connecting hole 103 is adapted to the diameter of the shank of the third fastening bolt, the width of the aforementioned third elongated hole 4101 is adapted to the diameter of the shank of the aforementioned third fastening bolt, and the length of the aforementioned third elongated hole 4101 is greater than the diameter of the shank of the aforementioned third fastening bolt. In practical applications, the shank of the third fastening bolt can pass through the third elongated hole 4101 and the third connecting hole 103, and the head of the third fastening bolt is located on the side of the second base plate 410 away from the top of the base 100. The third fastening nut is threadedly connected to the shank of the third fastening bolt and is located on the side of the base 100 away from the second base plate 410. For example, the specification of the aforementioned third fastening bolt may be M6×18.

[0103] It is understandable that, such as Figure 2 and Figure 12As shown, the number of the aforementioned third connecting holes 103 can be multiple, and these multiple third connecting holes 103 can be divided into multiple groups. Each group includes at least two third connecting holes 103 arranged at intervals along the emission direction, and the multiple groups are arranged at intervals along a direction perpendicular to the emission direction. The number of the aforementioned third elongated oval holes 4101 can also be multiple, and the number of third elongated oval holes 4101 is the same as the number of groups of third connecting holes 103. Each third elongated oval hole 4101 corresponds to a group of third connecting holes 103, and each third elongated oval hole 4101 corresponds to a third fastener 430. Based on this, on the one hand, when multiple third fasteners 430 are all provided on the base 100 and the second base plate 410, the limiting effect on the second base plate 410 can be improved; on the other hand, the position adjustment range of the support assembly 400 in the emission direction can also be expanded, which is beneficial for the aforementioned detection device to adapt to the detection operation of more specifications of holographic matched filters.

[0104] For example, the second vertical plate 420 can be screwed to the top of the second base plate 410. The specifications, type, and number of screws connecting the second vertical plate 420 and the second base plate 410 can be selected according to actual needs. For example, the screws connecting the second vertical plate 420 and the second base plate 410 can be, but are not limited to, two M6×18 socket head cap screws. The precision class of the threaded holes for mounting screws on the second vertical plate 420 and the second base plate 410 can be 7H.

[0105] For example, the second base plate 410 may be a generally rectangular plate structure, and the four corners of the second base plate 410 may be chamfered. The second vertical plate 420 may be a generally T-shaped plate structure, and the edges of the second vertical plate 420 may be chamfered.

[0106] For example, the parallelism of the two sides in the thickness direction of the second base plate 410 can be ensured by milling, and the thickness direction of the slot of the limiting slot 401 can be parallel to the two sides in the thickness direction of the second base plate 410. The slot of the limiting slot 401 can be formed at the top of the second vertical plate 420.

[0107] For example, such as Figure 13 As shown, the second vertical plate 420 may be provided with weight-reducing holes to reduce the overall weight of the second vertical plate 420 and the support assembly 400, which is beneficial to improving the mobility of the support assembly 400.

[0108] It is understandable that the dimensions and surface roughness of the second base plate 410 and the second vertical plate 420 can be set according to actual needs, and no further restrictions are imposed here.

[0109] In some examples, both the base 100 and the support assembly 400 are made of carbon steel, and both the surfaces of the base 100 and the support assembly 400 are coated with a black coating.

[0110] In this technical solution, both the aforementioned base 100 and the aforementioned support assembly 400 can be made of carbon steel, and both the surfaces of the base 100 and the support assembly 400 are coated with a black coating. Based on this, on the one hand, the structural stability and reliability of the base 100 and the support assembly 400 can be improved, extending their service life; on the other hand, it can also enhance the light absorption capacity of the support assembly 400 and the base 100, helping to reduce laser reflection at the testing site and further avoiding direct laser viewing by testing personnel.

[0111] For example, the base 100 can be made of 16# channel steel of grade Q235-C. A support surface can be milled on the open side of the channel steel. This support surface can be used to support the base on the ground or a testing platform in practical applications and can serve as a positioning reference for the machining of other surfaces during the base 100's machining process. A mounting surface can be milled on the side of the base 100 opposite to the support surface. This mounting surface is parallel to the support surface. In practical applications, the mounting surface can serve as the top of the base 100 and support other components of the aforementioned testing device. The surface of the base 100 can be treated with iron phosphate and then coated with black baking paint to form the aforementioned black coating, which can enhance the corrosion resistance of the base 100.

[0112] For example, the second base plate 410 and the second vertical plate 420 of the aforementioned support assembly 400 can be made of t12 steel plate with grade Q235-C. The surfaces of the second base plate 410 and the second vertical plate 420 can be coated with black baking paint after iron phosphate treatment to form the aforementioned black coating, which can enhance the corrosion resistance of the second base plate 410 and the second vertical plate 420.

[0113] For example, the first base plate 310, the first vertical plate 320, and the switch carrier plate 350 of the aforementioned laser emitting assembly 300 can be made of t12 steel plate with grade Q235-C. The surfaces of the first base plate 310, the first vertical plate 320, and the switch carrier plate 350 can be coated with black baking paint after iron phosphate treatment to form the aforementioned black coating, which can enhance the corrosion resistance of the first base plate 310, the first vertical plate 320, and the switch carrier plate 350.

[0114] In some examples, the target assembly 200 is made of aluminum and has a black anodized surface.

[0115] In this technical solution, the aforementioned target assembly 200 can be made of aluminum, and the surface of the target assembly 200 can be a black anodized surface. Based on this, on the one hand, the structural stability and reliability of the target assembly 200 can be improved, the service life of the target assembly 200 can be extended, and the weight of the target assembly 200 can be reduced, making it easier to move the target assembly 200; on the other hand, it can also improve the light absorption capacity of the target assembly 200, which is beneficial to reduce laser reflection at the testing site and further avoid the testing personnel looking directly at the laser; furthermore, it can also improve the color difference between the testing laser beam and the target surface 201, making it easier for the testing personnel to observe the imaging on the target surface 201.

[0116] For example, the base plate 210, target plate body 220, and stiffener 240 of the aforementioned target plate assembly 200 can all be made of t12 aluminum plate with grade 2A12-T4. The surfaces of the base plate 210, target plate body 220, and stiffener 240 can all be treated with black anodizing to form the aforementioned black anodized surface, which can enhance the corrosion resistance of the base plate 210, target plate body 220, and stiffener 240.
