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 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, adjusting the relative distance between reflector 1' and coupling mirror 2' can make the pupils coincide, and adjusting the azimuth and pitch angle of reflector 1' can make the optical axes coincide. In actual applications, the light beams are made to coincide 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 practical engineering, the performance of light sources entering a system can vary significantly (e.g., incident angle, spot aperture). Existing manual adjustments can adjust both the pupil and optical axis based on actual conditions. However, this process is complex, with poor alignment accuracy, requiring significant time and effort, and requiring high operator skill, making it unsuitable for repeated disassembly. While electrically adjustable mirrors can precisely adjust the azimuth and elevation of the reflected beam, they cannot adjust their relative position to the coupling mirror 2' when pupil deviation is significant, preventing beam alignment in the near field (i.e., pupil).

Of course, the structure of the moving member 2 is not limited to the above.
[0049] It should be noted that: not limited to the above-mentioned way of moving the moving member 2 relative to the first support member 1 by setting the linear displacement motor 7, but also through other structures, for example: the present structure also comprises a motor, a screw rod and a nut, etc., the motor drives the screw rod to rotate, and the screw rod is rotatably connected with the first support member 1, which 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 with the screw rod, and the nut can move along the screw rod, the moving member 2 is connected with the nut, of course, it is not limited to this, but also without any driving structure, directly make one of the moving member 2 and the first support member 1 set the slide rail, and the other set the slide block, the slide block and the slide rail are dampingly connected, etc., the specific design is according to the actual needs.
[0050] In this embodiment, preferably, as shown in Figures 2 to 5 The first adjusting member 4 is a piezoelectric bolt, and the first adjusting member 4 comprises a first fixed part 41 and a first telescopic part 42, and the first fixed part 41 is fixedly connected with the moving member 2, and the first telescopic part 42 is fixedly connected with the second support member 3, and the first telescopic part 42 can move relative to the first fixed part 41 and the moving member 2.

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 adopted. For example, the second fixing portion 51 of the second adjusting member 5 can be fixed to the movable member 2 by bolts, and the second telescopic portion 52 of the second adjusting member 5 can be spaced apart from the second movable member 2, so that the second telescopic portion 52 can freely expand and contract without interference.

[0074] Example 2
[0075] See also Figure 6 and Figure 7 As shown, the second embodiment of the present application further provides an optical system, including the adjustment device 100 described in the above-mentioned first embodiment, and thus has all the beneficial technical effects of the adjustment device 100, and the same technical features and beneficial effects are not repeated.
[0076] In this embodiment, preferably, Figure 6 and Figure 7 As shown, the second supporting member 3 of any adjusting device 100 is equipped with a transmitting mirror;
[0077] The optical system further includes a light source 200 and a coupling mirror 300; wherein the number of light sources 200 is 3 and they are sequentially arranged along the first preset direction a, and the light emitted by any light source 200 extends along the second preset direction b, wherein n=3;
[0078] Along the first preset direction a, the second to nth light sources 200 are each provided with an adjustment device 100 on one side thereof along the second preset direction b, and the first to n-1th light sources 200 are each provided with a coupling mirror 300 on one side thereof along the second preset direction b. The mirror surface of the reflector 6 mounted on the adjustment device 100 and the mirror surface of the coupling mirror 300 both intersect with the light emitted by the corresponding light source 200.
[0079] The coupling mirror 300 is arranged relative to the corresponding adjustment device 100 and close to the light source 200; the mirror surfaces of all the coupling mirrors 300 are arranged in parallel; the mirror surface of the reflector 6 installed on the adjustment device 100 is arranged in parallel with the mirror surface of the coupling mirror 300.
[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 light paths, the first light path 700, i.e., the first light source 201, is turned on. With the first light path 700 as the reference light path, the size of the variable aperture 400 is adjusted so that the first light path 700 just passes through the variable aperture 400 after being transmitted through the first coupling mirror 301. The position of the far-field target plate instrument is adjusted so that the light path forms a clear image 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 light 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 then just passes through the variable aperture 400. Adjust the first adjusting member 4 and the second adjusting member 5 of the second adjusting device 102 of the adjusting device 100 so that the light spot of the second optical path 800 on the far-field target plate instrument coincides with the light spot of the first optical path 700 on the far-field target plate instrument.
[0083] Turn on the third optical path 900, i.e., the third light source 203, and adjust the linear displacement motor 7 of the third adjustment device 103 so that the third optical path 900 passes through the variable aperture 400 after being reflected by the third adjustment device 103, the second coupling mirror 302, the second adjustment device 102 of the adjustment device 100, and the first coupling mirror 301. Adjust the first adjustment member 4 and the second adjustment member 5 of the third adjustment device 103 so that the light spot of the third optical path 900 on the far-field target plate instrument overlaps with the light spot of the first optical path 700 on the far-field target plate instrument.
[0084] Combined with the above, it can be seen that the three degrees of freedom of a certain light path can be adjusted at the same time, avoiding the situation where the directions cannot be overlapped due to insufficient adjustment freedom, thereby achieving rapid and precise overlap of the directions of multiple light sources 200, avoiding human adjustment errors, increasing the beam pointing accuracy, and reducing pupil overlap errors.

[0086] Furthermore, preferably, one side of the lens of any of the aforementioned coupling mirrors 300 is coated with an antireflection film, and the other side is coated with a reflective film.
[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 spots in the near field, and the far-field target spot meter 500 is used to observe the overlap of the light spots 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 beam direction.
[0089] Furthermore, preferably, the variable iris 400 can be manually adjusted in 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, light source 200, coupling mirror 300, and variable aperture 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, this is not limited to this, and the support frame 600 can also be omitted, depending on the actual design needs. In addition, it should be noted that the aforementioned far-field target spot analyzer 500 is relatively far away from the variable aperture 400, so it can be arranged outside the support frame 600 to avoid lengthening the support frame 600 as a whole.
[0092] Further, preferably, the support frame 600 is box-shaped, but is not limited thereto.
[0093] Furthermore, 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 toward the far-field target spot meter 500 .
