Abstract
Description
Technical Field
[0001] The present application relates to the technical field of optical systems, and in particular to an adjustment device and an optical system. Background Art
[0002] At present, in optical systems, it is often necessary to combine two or more light beams into one light beam with high overlap to meet practical needs. Figure 1 As shown, light source A and light source B are two independent light sources. Light source A is reflected by reflector 1' and then incident on coupling mirror 2'. Light source B passes through coupling mirror 2' and merges with light source A to form a beam of light. The synthesized light beam requires that the pupil and the optical axis coincide at the same time, that is, the near field and the far field coincide at the same time. The above-mentioned pupil and optical axis are collectively referred to as the direction of light. In engineering practice, the relative distance between reflector 1' and coupling mirror 2' can be adjusted to make the pupil coincide, and the azimuth and pitch angle of reflector 1' can be adjusted to make the optical axis coincide. In practical applications, the light beams are overlapped by manually adjusting the direction of reflector 1', or an electrically adjustable mirror is used as reflector 1', so that the light beam reflected by the electrically adjustable mirror coincides with another light beam.
[0003] In engineering practice, there are large differences in the performance of the light source entering the system (such as the incident angle and the aperture of the light spot). In the existing technical solution, manual adjustment can adjust the pupil and the optical axis at the same time according to the actual situation, but the adjustment process is complicated, the coincidence accuracy is poor, and it takes a lot of time and energy. It requires high ability of the operator and is not suitable for repeated disassembly. The solution using the electric adjustable mirror can accurately adjust the azimuth and pitch angle of the reflected light beam, but when the pupil deviation is large, it cannot adjust the relative position of itself and the coupling mirror 2', so it cannot meet the coincidence of the light beam in the near field (i.e., the pupil).

[0041] Refer to the following Figures 2 to 7 The adjustment device and the optical system according to some embodiments of the present application are described.
[0042] Embodiment 1
[0043] See also Figures 2 to 7 As shown, an embodiment of the present application provides an adjustment device 100, comprising: a first support member 1, a moving member 2, a second support member 3, a first adjustment member 4 and a second adjustment member 5; wherein the moving member 2 is disposed on the first support member 1 and can move relative to the first support member 1;
[0044] The second supporting member 3 is used to install the reflector 6, and the second supporting member 3 is connected to the movable member 2 through the first adjusting member 4 and the second adjusting member 5, and the first adjusting member 4 and the second adjusting member 5 can move relative to the movable member 2 so that the second supporting member 3 and the reflector 6 thereon rotate.

[0046] In this embodiment, preferably, Figures 2 to 5 As shown, the adjustment device 100 further includes a linear displacement motor 7 , which is disposed on the first supporting member 1 , and the moving member 2 is disposed on the moving portion of the linear displacement motor 7 , so that the moving member 2 can move along the guide rail portion of the linear displacement motor 7 .
[0047] According to the structure described above, it can be known that the linear displacement motor 7 is used to drive the moving member 2 to move, thereby driving the second support member 3 connected to the moving member 2 and the reflector 6 installed on the second support member 3 to move, and then the distance between the reflector 6 and the coupling mirror 300 can be adjusted to facilitate the overlap of the pupils. Moreover, the driving method of the linear displacement motor 7 is more intelligent, which reduces the tasks of the staff and helps to improve the adjustment efficiency and accuracy.
[0048] Further, preferably, the moving member 2 includes a bottom plate and two side plates, and the two side plates are respectively arranged on both sides of the bottom plate, and the two ends of the guide rail of the linear displacement motor 7 correspond to the two side plates one by one and are connected. Of course, the structure of the moving member 2 is not limited to the above.
[0049] It should be noted that: the method of moving the movable member 2 relative to the first support member 1 is not limited to the aforementioned method of setting up a linear displacement motor 7, and other structures can also be used. For example: the present mechanism also includes a motor, a lead screw and a nut, the motor drives the lead screw to rotate, and the lead screw is rotatably connected to the first support member 1, it can only rotate relative to the first support member 1, but cannot move relative to the first support member 1, the nut is threadedly connected to the lead screw, it can move along the lead screw, and the aforementioned movable member 2 is connected to the nut. Of course, it is not limited to this, and it is also possible not to cooperate with any driving structure, and directly set a slide rail for one of the movable member 2 and the first support member 1, and the other one is set with a slider, the slider is connected to the slide rail in a damping sliding manner, etc., and the specific design is based on actual needs.

[0053] It can be seen that the two-dimensional deflection motion adjustment structure composed of two piezoelectric bolts is combined with the precision linear displacement motor 7 to form a three-degree-of-freedom pointing adjustment mechanism that can simultaneously adjust the light beam pupil and the optical axis.
[0054] Further, preferably, the first adjusting member 4 is formed with a first threaded through hole, the first fixing portion 41 is formed with a first threaded plug-in tube portion, and the first threaded plug-in tube portion is threadedly connected to the first threaded through hole, and the first telescopic portion 42 can extend to the second supporting member 3 via the first threaded plug-in tube portion, and is connected to the second supporting member 3. Of course, the assembly structure of the first adjusting member 4 and the second supporting member 3 is not limited to this, and other assembly structures can also be used, for example: the first fixing portion 41 of the first adjusting member 4 can also be fixed to the moving member 2 by bolts, and the first telescopic portion 42 of the first adjusting member 4 is spaced apart from the first moving member 2, so that the first telescopic portion 42 can be freely telescopic without interference.
[0055] Further, preferably, the second adjusting member 5 is formed with a second threaded through hole, the second fixing portion 51 is formed with a second threaded plug-in tube portion, and the second threaded plug-in tube portion is threadedly connected to the second threaded through hole, and the second telescopic portion 52 can extend to the second supporting member 3 via the second threaded plug-in tube portion, and is connected to the second supporting member 3. Of course, the assembly structure of the second adjusting member 5 and the second supporting member 3 is not limited to this, and other assembly structures can also be used, for example: the second fixing portion 51 of the second adjusting member 5 can also be fixed to the movable member 2 by bolts, and the second telescopic portion 52 of the second adjusting member 5 is spaced apart from the second movable member 2, so that the second telescopic portion 52 can be freely telescopic without interference.

[0057] In this embodiment, preferably, Figure 6 As shown, the adjusting device 100 further includes a signal controller 8, and the signal controller 8 is communicatively connected with the linear displacement motor 7 or the first adjusting member 4 and the second adjusting member 5 respectively.
[0058] According to the structure described above, the first adjusting member 4 and the second adjusting member 5, that is, the two piezoelectric bolts, can automatically extend or shorten after receiving the adjustment signal from the signal controller 8, and finally drive the reflector 6 to deflect in the pitch direction, thereby driving the reflector 6 to deflect at an angle in the pitch direction, with a sensitivity better than 1μrad; the linear displacement motor 7 provides linear displacement power after receiving the displacement signal from the signal controller 8, and the displacement error is less than 0.05mm.
[0059] It can be seen that the azimuth and elevation angles of the reflector 6 are adjusted by two piezoelectric bolts, and the sensitivity is better than 1μrad. The relative position of the reflector 6 and the coupling mirror 300 is adjusted by the linear displacement motor 7, and the displacement error is less than 0.05mm. In other words, the three degrees of freedom of a certain optical path can be adjusted at the same time, avoiding the situation where the directions cannot be overlapped due to insufficient adjustment freedom, thereby achieving fast and precise overlap of the directions of multiple light sources 200, avoiding human adjustment errors, and increasing the beam pointing accuracy. The optical axis coincidence error is ≤10μrad, and a signal controller 8 can be provided, which has a high degree of automation and greatly improves the adjustment efficiency. Of course, the signal controller 8 may not be provided.

Such a structure makes it easier to install the reflector 6 in the aforementioned mounting hole 31, thereby improving the convenience of operation.
[0062] Further, preferably, the second supporting member 3 is a plate-like structure, and preferably, it can be an L-shaped plate, of course, not limited thereto, it can also be a block or other structure.
[0063] It should be noted that the mounting structure of the reflector 6 and the second supporting member 3 is not limited to the above, and the reflector 6 may be directly mounted on the side wall surface of the second supporting member 3 and then fixed with fastening members such as screws or bolts.

[0068] It should be noted that the installation method of the first supporting member 1 and the target site is not limited to this, and can also be connected by means of buckles and slots or plugging, welding, gluing, etc., which is specifically designed according to actual needs.

[0080] According to the structure described above, the adjustment process of this optical system is as follows:
[0081] When adjusting the directions of the three-path light, open the first light path 700, that is, the first light source 201, take the first light path 700 as the reference light path, adjust the size of the variable aperture 400, so that the first light path 700 just passes through the variable aperture 400 after being transmitted by the first coupling mirror 301, and adjust the position of the far-field target plate instrument so that the light path can be clearly imaged on the target plate instrument.
[0082] Open the second optical path 800, i.e., the second light source 202, and adjust the linear displacement motor 7 of the second adjusting device 102 of the adjusting device 100 so that the optical path passes through the second coupling mirror 302 and is reflected by the second adjusting device 102 of the adjusting device 100 and the first coupling mirror 301 and just passes through the variable aperture 400.

[0087] In this embodiment, preferably, Figure 6 As shown, the optical system also includes a variable aperture 400 and a far-field target spot meter 500; wherein the variable aperture 400 and the far-field target spot meter 500 are sequentially arranged on one side of the first light source 200 along the second preset direction b, and the variable aperture 400 is arranged close to the light source 200; the variable aperture 400 and the far-field target spot meter 500 both intersect with the light emitted by the first light source 200.
[0088] According to the structure described above, the variable aperture 400 is used to observe the overlap of the light spot in the near field, and the far-field target spot meter 500 is used to observe the overlap of the light spot in the far field. It can be seen that the variable aperture 400 and the far-field target plate meter are used to simultaneously monitor the overlap of the light path in the near field and the far field, providing an error correction reference for the two piezoelectric screws and the linear displacement motor 7, thereby quickly adjusting the light beam direction.
[0089] Further, preferably, the variable iris 400 can manually adjust the iris size to allow the light path to pass through or partially pass through, so as to observe the overlap of the light spots in the near field.
[0090] Further, preferably, the moving direction of the moving member 2 of the adjusting device 100 forms an angle with the second preset direction b.
[0091] In this embodiment, preferably, Figure 6 and Figure 7 As shown, the optical system further includes a support frame 600, and the adjustment device 100, the light source 200, the coupling mirror 300 and the variable iris 400 are all mounted on the support frame 600. It can be seen that the integration is high and the overall movement is convenient. Of course, it is not limited to this, and the support frame 600 may not be provided, and the specific design is based on actual needs. In addition, it should be noted that the aforementioned far-field target spot meter 500 is relatively far away from the variable iris 400, so it can be arranged outside the support frame 600 to avoid the overall lengthening of the support frame 600.
[0092] Further, preferably, the support frame 600 is box-shaped, but is not limited thereto.
[0093] Further, preferably, the support frame 600 is formed with a light through hole, and the light through hole corresponds to the aforementioned far-field target spot meter 500 . It can be seen that the light passing through the light through hole will be emitted to the far-field target spot meter 500 .
