[0028] refer to Figures 1 to 6 According to the present embodiment, the detection device 100 may include a mounting structure 10 and a plurality of measurement units 90 , wherein the mounting structure 10 is arranged on the upper portion of the detection object 1 , and the plurality of measurement units 90 are mounted on the mounting structure 10 to measure the detection object 1 .

[0029] The measuring unit 90 may be a unit capable of judging the quality of resolution of the lens as the inspection object 1 by the MTF (Modulation Transfer Function) value.

[0030] MTF is a value obtained by quantifying the black-white contrast according to the spatial frequency, and is a representative value indicating the resolution of a camera. As a value representing the resolution, it is widely used as a main parameter for judging the performance of a lens.

[0031] The measurement unit 90 of the present embodiment may use various devices as long as the quality of the lens resolution can be judged by the MTF value, and is not limited in shape and structure.

[0032] A plurality of measurement units 90 are fixed and fastened to the mounting structure 10. In the present embodiment, the measurement units 90 are fixed to the mounting structure 10 using a fixing member such as a bolt. However, this is not limited thereto, and as long as the measurement units 90 can be detachably coupled to the mounting structure 10, various well-known methods may be used.

[0033] The mounting structure 10 is a structure for fixing the plurality of measurement units 90 so that the plurality of measurement units 90 are arranged toward the inspection object 1 , and may be arranged at a certain distance from the inspection object 1 .

[0034] In the present embodiment, the mounting structure 10 may be formed in a dome shape or a hemispherical shape as a whole, and may include a support portion 20 and a plurality of support frames 80 .

[0035] The support portion 20 is formed in a ring shape, and is disposed at the lowermost portion of the mounting structure 10 to support the support frame 80 as a whole.

[0036] The support portion 20 may have fastening holes H1 to H8 to which the support frame 80 is coupled. The fastening holes H1 to H8 may be provided in plural in correspondence with a plurality of coupling positions to which the support frame 80 is coupled.

[0037] refer to Figure 5 and Figure 6 The mounting structure 10 of the present embodiment may be divided into four regions by a base frame 39 described later. In addition, the plurality of fastening holes H1 to H8 may be dispersedly arranged in each of the divided regions.

[0038] More specifically, the support portion 20 of the present embodiment includes four first fastening holes H1 in the support frame 80 for fastening the fixing frame 30. The first fastening holes H1 are arranged at equal intervals on the support portion 20. Therefore, by the fixing frame 30 coupled to the four first fastening holes H1, the support portion 20 and the internal space of the support portion 20 are divided into four parts having the same size.

[0039] In each divided area, the second to eighth fastening holes H2 to H8 are arranged at a certain distance. The second to eighth fastening holes H2 to H8 may be arranged in a line ( Figure 6 The layout is carried out in a line-symmetrical manner based on C).

[0040] The second fastening hole H2 to the eighth fastening hole H8 can be used to fasten the spoke frame including the first reference frame 40, the second reference frame 50 and the auxiliary frame 60 described later. Figure 3 , Fig.12 and Fig.13 As shown, the first reference frame 40 can be fastened to the fifth fastening hole H5, and the second reference frame 50 can be fastened to the sixth fastening hole H6 or the seventh fastening hole H7. In addition, the auxiliary frame 60 can be selectively fastened to the second fastening hole H2, the third fastening hole H3, the fourth fastening hole H4, and the eighth fastening hole H8.

[0041] The other end of the auxiliary frame 60 coupled to the second fastening slit 35 described later is coupled to the second to fourth fastening holes H2 to H4 . Therefore, the second to fourth fastening holes H2 to H4 may be arranged at positions radially opposite to the second fastening slit 35 .

[0042] The other ends of the reference frames 40 and 50 coupled to the first fastening slit 34 and the other ends of the auxiliary frame 60 coupled to the third fastening slit 89 described later are coupled to the fifth to eighth fastening holes H5 to H8. Therefore, the fifth to eighth fastening holes H5 to H8 can be arranged at positions radially opposite to the first fastening slit 34.

[0043] In addition, the other end of the first reference frame 40 is coupled to the fifth fastening hole H5. In this embodiment, since the first reference frame 40 is arranged to divide the segmentation area into two parts, the fifth fastening hole H5 may be arranged in the middle of dividing the area between the two first fastening holes H1 into two parts.

[0044] The detailed positions of the second to eighth fastening holes H2 to H8 or the intervals between the fastening holes H2 to H8 can be defined based on the azimuth angle described later. The configuration related to this will become more clear through the description of the spoke frame described later.

[0045] The coupling between the support frame 80 and the support portion 20 may use an additional fixing member such as a bolt. However, it is not limited thereto.

[0046] As a frame coupled to the support part 20 , the support frame 80 may be coupled to the support part 20 to form a radial and dome form.

[0047] The support frame 80 of the present embodiment may include a base frame 39 and a spoke frame.

[0048] The base frame 39 includes a central portion 38 and a plurality of fixed frames 30, wherein the central portion 38 is arranged on the central axis of the support portion 20, and the plurality of fixed frames 30 extend slenderly in multiple directions from the central portion 38. In the present embodiment, although the case where there are four fixed frames 30 is taken as an example, the number of fixed frames 30 can be changed as needed.

[0049] The distal end of the fixing frame 30 is fastened to the first fastening hole H1 of the support portion 20. Therefore, one end of the fixing frame 30 is connected to the central portion 38, and the other end is connected to the support portion 20.

[0050] As described above, the mounting structure 10 of the present embodiment is formed in a dome shape. Therefore, the center portion 38 and the support portion 20 are not arranged on the same plane, and the fixing frame 30 is formed in an arc shape to connect the center portion 38 and the support portion 20.

[0051] All the support frames 80 (including the fixed frame 30 ) have guide grooves 85 inside. The guide grooves 85 may be formed in the form of through holes, and may be formed in the form of slits elongated along the longitudinal direction of the support frame 80 .

[0052] Such a guide groove 85 can be coupled to the aforementioned measuring unit 90. For example, a fixing member such as a bolt can penetrate the guide groove 85 and be fastened to the measuring unit 90, whereby the measuring unit 90 can be arranged at various positions within the range in which the guide groove 85 is formed. That is, the operator can select the position of the measuring unit 90 along the guide groove 85 for arrangement.

[0053] The center portion 38 may have a central slit 85a inside. The central slit 85a may be arranged on the central axis of the support portion 20 and used as a hole for coupling the measuring unit 90 in the same manner as the guide groove 85. Therefore, the central slit 85a may be formed as a through hole in the form of a short slit that allows the measuring unit 90 to be moved and arranged.

[0054] Furthermore, the center portion 38 of the present embodiment may include a coupling portion 31 .

[0055] The coupling part 31 may be disposed between two fixing frames 30. Therefore, in the base frame 39 of the present embodiment, each space between four fixing frames 30 may have one coupling part 31, and a total of four coupling parts 31 may be provided.

[0056] The coupling part 31 supports one end of the spoke frame and is coupled to the spoke frame. To this end, each coupling part 31 may include an inner coupling part 32 and an outer coupling part 33, wherein the inner coupling part 32 is provided with a first fastening slit 34, and the outer coupling part 33 is formed with a second fastening slit 35.

[0057] The inner joint portion 32 may be formed in a form extending from the center portion 38 toward the support portion 20 and connected to the center portion 38 and the two fixing frames 30. Spoke frames (eg, reference frames 40 and 50) are mounted and coupled to the inner joint portion 32.

[0058] The outer joint portion 33 may be formed to extend from the inner joint portion 32 toward the support portion 20 and configured to be connected to any one of the two fixing frames 30. The spoke frame (eg, the auxiliary frame 60) is mounted and coupled to the outer joint portion 33.

[0059] like Figure 6 As shown, in the present embodiment, one outer joint portion 33 is provided between each of the fixing frames 30, and a total of four outer joint portions 33 are provided. In addition, the four outer joint portions 33 are connected to only two of the four fixing frames 30. Therefore, the outer joint portion 33 is not connected to the remaining two fixing frames 30.

[0060] Here, the fixing frames 30 connected to the outer joint part 33 may be two fixing frames 30 arranged in a straight line with the plane of the base frame 39 as a reference, and may be fixing frames 30 arranged in a direction perpendicular to the length direction of the central slit 85a. However, it is not limited thereto.

[0061] The first fastening slit 34 and the second fastening slit 35 are each formed in the form of a through hole, and are formed in the form of a slit in an arc shape concentric with the support portion 20 .

[0062] Fig.10 is partially shown Figure 2 FIG. 1 is a diagram of a lower surface of a joint portion of a mounting structure shown in FIG. 1 , and Fig.11 It is along Fig.10 II is a cross-sectional view taken from FIG.

[0063] Also refer to Fig.10 and Fig.11 , the first fastening slit 34 is formed in the inner joint portion 32, and the second fastening slit 35 is formed in the outer joint portion 33. Therefore, the first fastening slit 34 and the second fastening slit 35 are arranged at a distance in the radial direction.

[0064] The reference frames 40 and 50 described later are coupled to the first fastening slit 34, and the auxiliary frame 60 having a relatively short length is coupled to the second fastening slit 35. Therefore, the distance between the first fastening slit 34 and the support portion 20 may be formed to be greater than the distance between the second fastening slit 35 and the support portion 20.

[0065] The coupling portion 31 is a portion coupled to one end of a spoke frame described later, and therefore, the specific shape may be configured to correspond to the shape of the end portion of the spoke frame.

[0066] Furthermore, since the first fastening slit 34 and the second fastening slit 35 are formed in the form of slits, the position of the spoke frame can be corrected in a state where the spoke frame is coupled to the first fastening slit 34 or the second fastening slit 35. Fig.12 As shown, in a state where one end of the second reference frame 50 described later is arranged on the first fastening slit 34 and the other end is arranged on the sixth fastening hole H6, when Fig.13 When the other end is coupled to the seventh fastening hole H7 in the state shown, the fixing member 82 coupled to the first fastening slit 34 does not need to be completely separated from the coupling portion 31, but only needs to loosen the fixing member 82 (for example, a bolt and a nut) to the extent that it can slide, and the fixing member 82 can be arranged in an appropriate position by moving it along the length direction of the first fastening slit 34.

[0067] To this end, the first fastening slit 34 may include a through portion 34 a formed on a first surface side contacting the reference frames 40 and 50 and a receiving portion 34 b formed on a second surface side which is an opposite surface to the first surface.

[0068] In addition, the width of the accommodation portion 34b may be formed to be greater than the width of the through portion 34a. For example, the first fastening slit 34 may be formed in a form in which the width increases in a direction toward the accommodation portion 34b.

[0069] like Fig.12 As shown, the nut N may be inserted into the accommodation portion 34b formed on the second surface of the coupling portion 31. The nut N may be entirely disposed in the accommodation portion 34b without protruding to the outside of the coupling portion 31.

[0070] The through portion 34a is formed to have a width capable of inserting the bolt B, and the width of the through portion 34a is formed to be smaller than the width of the nut N. Therefore, when the bolt B is coupled to the nut N arranged in the accommodation portion 34b, the nut N is arranged and fixed in the accommodation portion 34b without passing through the through portion 34a.

[0071] In the case where the nut N is arranged to protrude from the lower surface of the coupling part 31 to the outside, the protruding nut N and the measuring unit 90 coupled to the support frame 80 may interfere with each other. Therefore, the coupling position of the measuring unit 90 may be limited.

[0072] However, in the present embodiment, since the nut N is completely arranged inside the coupling portion 31 , the above-mentioned problem can be solved.

[0073] In addition, as described above, even if the bolt B and the nut N are not completely separated and one end of the second reference frame 50 slides, the nut N can move while being arranged in the accommodation portion 34b, thereby preventing interference between the nut N and the measurement unit 90.

[0074] This configuration can also be similarly applied to the second fastening slit 35 or the third fastening slit 89 described later, which are formed in a slit shape, and the spoke frame (for example, the auxiliary frame 60) coupled thereto.

[0075] refer to Figure 5 In the present embodiment, the second fastening slit 35 is formed in a slit shape having a shorter length than the first fastening slit 34. However, the configuration of the present invention is not limited thereto.

[0076] The base frame 39 and the support portion 20 according to the present embodiment configured as above can be configured to be point-symmetrical with respect to the central slit 85 a and line-symmetrical with respect to the fixed frame 30 .

[0077] Figures 7 to 9 : is a figure which shows the spoke frame according to this embodiment.

[0078] Referring to these figures at the same time, the spoke frame is similarly constructed as the aforementioned fixing frame 30 and is detachably coupled to the support portion 20. In addition, it can be selectively coupled to the aforementioned second to eighth fastening holes H2 to H8. Therefore, it can be selectively arranged at a plurality of coupling positions having different angles with the fixing frame 30.

[0079] Each spoke frame is formed in an arc shape like the fixed frame 30, and one end is arranged on the center portion 38 side, and the other end is fastened to the support portion 20. To this end, both ends of the spoke frame may be provided with through holes 86 and 87, respectively.

[0080] The spoke frame may be formed with a guide groove 85 inside. The guide groove 85 may be formed to penetrate the spoke frame in the form of an elongated slit along the length direction of the spoke frame.

[0081] The aforementioned measuring unit 90 may be coupled to the guide groove 85 of the spoke frame similarly to the fixing frame 30. For example, a fixing member such as a bolt may penetrate the guide groove 85 and be fastened to the measuring unit 90, whereby the measuring unit 90 may be arranged at various positions along the guide groove 85.

[0082] One end of the spoke frame may be coupled to the base frame 39 through the first to third fastening slits 34 to 89 formed in the coupling portion 31 or the auxiliary coupling portion 88. In addition, the other end of the spoke frame may be coupled to the support portion 20 through the second to eighth fastening holes H2 to H8.

[0083] Each spoke frame may be coupled to the base frame 39 using an additional fixing member 82 such as a bolt and a nut. For example, after the bolt is inserted to sequentially penetrate the through hole 86 of the spoke frame and one of the fastening slits 34, 35, and 89, a nut may be coupled to the end of the bolt, thereby fixing and fastening the spoke frame to the base frame 39. In this case, even if the bolt and the nut are not completely separated, one end of the spoke frame may be moved along the length direction of the fastening slits 34, 35, and 89. Therefore, it is very easy to change the coupling position of the spoke frame.

[0084] The spoke frame may be formed so that the thickness of the portion overlapping the coupling portion 31 or the auxiliary coupling portion 88 is relatively thinner than other portions. Therefore, when the spoke frame is coupled to the base frame 39, the spoke frame may not protrude from the base frame 39 and form a smooth hemispherical shape together with the fixing frame 30.

[0085] The spoke frames may be divided into basic frames 40 and 50 and an auxiliary frame 60 according to shapes and lengths.

[0086] One end of the reference frames 40 and 50 may be fastened to the central portion 38 , and divided into a first reference frame 40 and a second reference frame 50 according to whether or not there is an auxiliary coupling portion 88 .

[0087] Figure 7 is a diagram showing a first reference frame according to the present embodiment, Figure 8 is a diagram showing a second reference frame according to the present embodiment, and Fig. 9 2 is a diagram showing a third reference frame according to the present embodiment.

[0088] Referring to these figures simultaneously, the first reference frame 40 includes an auxiliary joint portion 88. The auxiliary joint portion 88 is configured similarly to the aforementioned outer joint portion 33, and is formed integrally with the first reference frame 40.

[0089] One end of the first reference frame 40 is coupled to the first fastening slit 34 provided in the coupling portion 31. In addition, the other end of the first reference frame 40 is coupled to a fifth fastening hole H5 provided in the support portion 20.

[0090] When the first reference frame 40 is coupled to the base frame 39, the outer coupling portion 33 and the auxiliary coupling portion 88 are respectively arranged on both sides of the first reference frame 40. Therefore, the auxiliary coupling portion 88 can be arranged on the first reference frame 40 in the following form: that is, when the first reference frame 40 is coupled to the base frame 39, the auxiliary coupling portion 88 is arranged at a position opposite to the outer coupling portion 33 in a form that is line-symmetrical with the outer coupling portion 33.

[0091] The auxiliary coupling portion 88 may be formed with a third fastening slit 89. When the first reference frame 40 is coupled to the base frame 39, the third fastening slit 89 may be arranged to be line-symmetrical with the second fastening slit 35.

[0092] Therefore, when the first reference frame 40 is coupled to the base frame 39 , the third fastening slit 89 is formed as an arc-shaped slit that is concentric with the second fastening slit 35 and has the same radius, and therefore, the distance between the second fastening slit 35 and the support portion 20 is constructed to be the same as the distance between the third fastening slit 89 and the support portion 20 .

[0093] like Figure 3 As shown, in each divided area generated by the fixing frame 30 , the first reference frame 40 may be combined with two auxiliary frames 60 .

[0094] More specifically, within a divided space defined by the space between the two adjacently arranged fixed frames 30, the first reference frame 40 may be coupled to the support portion 20 in a form that divides the divided space into two parts. In addition, the two auxiliary frames 60 may be coupled to the support portion 20 in a form that divides the space between the first reference frame 40 and the fixed frame 30 into two parts. At this time, one end of one auxiliary frame 60 is fastened to the second fastening slit 35, and one end of the other auxiliary frame 60 may be fastened to the third fastening slit 89.

[0095] In this case, the angle between the first reference frame 40 and the fixed frame 30 may be 45°. Here, the angle may actually refer to an azimuth angle. Figure 3 The mounting structure 10 shown may be used for 1:1 ratio measurements with an azimuth angle of 45°.

[0096] On the other hand, in the present embodiment, the first reference frame 40 may include two forms in which the auxiliary joint portions 88 are arranged in opposite directions with respect to the guide groove 85. For example, Figure 7 (b) shows the form 40a and Figure 7 (c) and 40b shown in FIG. Figure 3 As shown, the first reference frames 40 of the two forms 40 a and 40 b can be selectively combined according to the positions at which the outer combining parts 33 are arranged.

[0097] The second reference frame 50 is similarly constructed as the first reference frame 40 and does not have the auxiliary joint portion 88 ( Figure 7 ).

[0098] Therefore, one end of the second reference frame 50 may be coupled to the first fastening slit 34 provided in the coupling portion 31. Fig.12 and Fig.13 As shown, the other end of the second reference frame 50 may be coupled to the sixth fastening hole H6 or the seventh fastening hole H7.

[0099] In one divided area, the second reference frame 50 may not be coupled to the support portion 20 together with the first reference frame 40, but one of the first reference frame 40 and the second reference frame 50 may be selectively coupled to the support portion 20. In addition, the second reference frame 50 may be coupled together with at least one auxiliary frame 60.

[0100] The auxiliary frame 60 may be formed to have a shorter length than the reference frames 40 and 50 and fastened between the reference frames 40 and 50 and the fixing frame 30 .

[0101] One end of the auxiliary frame 60 may be coupled to the second fastening slit 35 provided in the coupling portion 31 or to the third fastening slit 89 provided in the first reference frame 40. In addition, the other end of the auxiliary frame 60 may be changed depending on the position to which the one end of the auxiliary frame 60 is coupled.

[0102] In the case of coupling one end of the auxiliary frame 60 to the second fastening slit 35 , the other end of the auxiliary frame 60 may be coupled to any one of the second fastening hole H2 , the third fastening hole H3 , and the fourth fastening hole H4 .

[0103] For example, Figure 3 As shown, in a case where the auxiliary frame 60 is coupled together with the first reference frame 40 , when one end of the auxiliary frame 60 is coupled to the second fastening slit 35 , the other end of the auxiliary frame 60 may be coupled to the second fastening hole H2 .

[0104] In addition, if Figure 12 to Figure 13 As shown, in the case where the auxiliary frame 60 is coupled together with the second reference frame 50 , one end of the auxiliary frame 60 may be coupled to the second fastening slit 35 , and the other end may be coupled to the third fastening hole H3 or the fourth fastening hole H4 .

[0105] On the other hand, Figure 3 As shown, in a case where the auxiliary frame 60 is coupled together with the first reference frame 40 and one end of the auxiliary frame 60 is coupled to the third fastening slit 89 , the other end of the auxiliary frame 60 may be coupled to the eighth fastening hole H8 .

[0106] At least one of the spoke frames of the mounting structure 10 of the present embodiment configured in this way can be selectively coupled to a plurality of coupling positions. Here, the plurality of coupling positions refer to positions each having a different azimuth angle.

[0107] Therefore, the spoke frame may be selectively combined with the base frame 39 for use according to the type or structure of the inspection object 1 , and thus the measurement unit 90 may be arranged at an optimal position corresponding to the type or structure of the inspection object 1 .

[0108] This will be described in more detail below.

[0109] Fig.12 is a plan view of a mounting structure for arranging measurement units in a ratio of 4:3, and Fig.13 is a plan view of a mounting structure for arranging measurement units at a ratio of 16:9. In addition, Figure 3 This is a plan view of a mounting structure for arranging measurement units at a 1:1 ratio.

[0110] When the size or type of the lens of the detection object 1 is different, the azimuth angle of the measurement unit 90 needs to be changed. Therefore, the present embodiment provides a mounting structure 10 capable of arranging the measurement unit 90 at various azimuth angles (45°, 36.87°, 29.36°, etc.).

[0111] For example, Figure 3 As shown, the first reference frame 40 may be coupled to the base frame 39, and the auxiliary frames 60 may be respectively arranged on both sides of the first reference frame 40. In this case, since the angle between the fixed frame 30 and the first reference frame 40 is 45°, and the angle between the fixed frame 30 and the auxiliary frame 60 is 22.5°, the measuring unit 90 may be arranged at a ratio of 1:1 (azimuth angle 45°).

[0112] For example, Fig.12 As shown, when the auxiliary frame 60 and the second reference frame 50 are coupled to the base frame 39, the other end of the auxiliary frame 60 is coupled to the third fastening hole H3, and the other end of the second reference frame 50 is coupled to the sixth fastening hole H6, since the angle between the fixed frame 30 and the second reference frame 50 is 36.87°, and the angle between the fixed frame 30 and the auxiliary frame 60 is 26.57°, the measuring unit 90 can be arranged at a ratio of 4:3 (azimuth angle 36.87°).

[0113] For example, Fig.13 As shown, when the auxiliary frame 60 and the second reference frame 50 are coupled to the base frame 39, the other end of the auxiliary frame 60 is coupled to the fourth fastening hole H4, and the other end of the second reference frame 50 is coupled to the seventh fastening hole H7, since the angle between the fixed frame 30 and the second reference frame 50 is 29.36°, and the angle between the fixed frame 30 and the auxiliary frame 60 is 30.32°, the measuring unit 90 can be arranged at a ratio of 16:9 (azimuth angle 29.36°).

[0114] In this way, the mounting structure 10 according to the present embodiment can perform detection and measurement at various azimuth angles by selectively coupling the spoke frame to the base frame 39. Therefore, since there is no need to replace the entire mounting structure in order to detect or measure the detection object 1 at different azimuth angles, it is very easy to perform measurement, and the measurement time can also be minimized.

[0115] Furthermore, it is possible to minimize the time consumed in the parallelism inspection process performed along with the replacement of the mounting structure or in the process of repeatedly separating and bonding the measuring unit from and to the mounting structure.

[0116] In addition, the present invention is not limited to the above-mentioned embodiment, but various modifications can be made.

[0117] Fig.14 and Fig.15 The present invention is a partially exploded perspective view schematically showing a mounting structure of a detection device according to another embodiment of the present invention.

[0118] exist Fig.14 and Fig.15 In the mounting structure of the embodiment shown, at least one of the fastening holes H2 to H8 provided in the support portion 20 is formed in a slit form. For example, the third fastening hole H3 to the fourth fastening hole H4 are connected to each other and arranged in one slit S1, and the sixth fastening hole H6 to the seventh fastening hole H7 are also connected to each other and arranged in one slit S2.

[0119] That is, the fastening holes H6 to H7 for position change of the second reference frame 50 and the fastening holes H3 to H4 for position change of the auxiliary frame 60 are respectively configured to be connected to each other and arranged in one slit S1 and S2 .

[0120] In this case, similarly to the first fastening slit 34 to the second fastening slit 35 , the position of the spoke frame (eg, the reference frames 40 and 50 ) coupled to the support portion 20 side can be changed by sliding.

[0121] exist Fig.14In the mounting structure of the detection device 200 shown, the width of the slits S1 and S2 connecting the fastening holes is formed to be greater than or equal to the diameter of the fastening holes H3, H4, H6 and H7. In this case, the fixing member 84 coupled to the fastening holes H3, H4, H6 and H7 can be configured to include bolts and nuts in the same manner as the fixing member 82 coupled to the first fastening slit 34, the second fastening slit 35 and the third fastening slit 89.

[0122] Therefore, when changing the position of the auxiliary frame 60 coupled to the position of the third fastening hole H3, it is not necessary to completely separate the fixing member 84 coupled to the corresponding position from the support portion 20, but only to loosen the fixing member 84 (e.g., bolts and nuts) to a degree that it can slide, and then arrange the fixing member 84 along the slit S1 at the position corresponding to the fourth fastening hole H4 and fix it. Therefore, it is very easy to change the position of the spoke frame (e.g., the reference frames 40 and 50).

[0123] exist Fig.15 In the mounting structure of the detection device 300 shown, the widths of the slits S1 and S2 connecting the fastening holes H3 , H4 , H6 , and H7 may be formed to be smaller than the diameters of the fastening holes H3 , H4 , H6 , and H7 .

[0124] In addition, the fixing member 84 can be partially formed to have a smaller thickness in the radial direction by removing a portion of the cylindrical shaft portion 84a inserted into the slits S1 and S2. For example, the minimum thickness of the shaft portion 84a can be less than or equal to the width of the slits S1 and S2.

[0125] Therefore, the fixing member 84 can move along the slits S1 and S2 after rotating the shaft portion 84a so that the shaft portion 84a is inserted into the slits S1 and S2. In addition, when located in the fastening holes H3, H4, H6 and H7, the shaft portion 84a can be rotated to couple the fixing member 84 to the fastening holes H3, H4, H6 and H7.

[0126] Therefore, the fixing member 84 according to the present embodiment may not include a nut. However, it is not limited thereto.

[0127] In the mounting structure of the present embodiment thus configured, since the positions of the fastening holes H3 , H4 , H6 , and H7 within the slits S1 and S2 are clearly distinguished, the spoke frame can be easily arranged at a desired position.

[0128] Although the embodiments of the present invention are described in detail above, the scope of rights of the present invention is not limited thereto, and it is obvious to those skilled in the art that various modifications and variations can be made without departing from the technical idea of ​​the present invention described in the claims.

[0129] For example, although the mounting structure disclosed in the aforementioned embodiment is formed into a dome shape as an example, it can also have various deformations such as being formed into a plane shape. In addition, although the detection device of the aforementioned embodiment is described by taking the case of measuring the MTF value of a lens as an example, it can also be widely applied to various other detection devices.

[0130] Furthermore, the various embodiments may be implemented in combination with each other.
