Abstract
The invention discloses a three-dimensional adjusting device for remote sensing instrument offsetting image rotation K mirror, the device includes: inner ring, outer ring, upper regulation rack, triangle mirror fixing rack, locking bolt, regulating bolt and adjusting cam. The left-right movement, pitching movement, up-down movement and yaw regulation of triangle mirror are realized by regulating bolt and cam. The space position of K mirror in the optics system is adjusted, and after the regulation is done, the whole structure is fixed by locking bolt. Three-dimensional regulation device has high precision and good stability, which can avoid mirror stress deformation induced by regulating operation.
Description
Technical field
The present invention relates to three-dimensional regulating mechanism fixing in the optical system, that adjust optical element, specifically be meant the used three-dimensional regulating mechanism of three angle mirrors in the picture rotation K mirror that disappears in the space remote instrument optical system.
Technical background
Along with the development of space remote sensing technology, space remote instrument develops towards the direction of high detection sensitivity, and detector is also developed to polynary alignment direction by the unit.Yet, at multiunit detector and sweep in the mode,, in use can run into picture and revolve problem for the optical mechaical scanning instrument that adopts 45 ° of rotation sweep scanning mirror patterns.In order to address this problem, people introduce one three reflecting surface optical system behind 45 ° of scanning mirrors, when its corner remains a half of 45 ° of scanning mirror corners, as not rotating, reach and eliminate the purpose that kine bias is changeed.Be made up of two optical elements because of three reflecting surface optical systems, one is three angle mirrors, and another is a level crossing, and its three reflecting surface is " K " word arrangement, so give a name " K mirror ", as shown in Figure 1.
The installation position of K mirror in optical system is equipped with strict requirement, and following 3 points are specifically arranged:
1. strict guarantee three angle mirror θ angular vertexs and flat mirror reflects identity distance are from the relation of d, and this is guaranteed by processing;
2.K the mirror turning axle will overlap with the primary optical system optical axis is strict, this light requirement school is regulated;
3.K the mirror optical axis will overlap with the primary optical system optical axis is strict, this light requirement school is regulated;
Therefore, when the Adjustment System light path, about needing to carry out, pitching, driftage three-dimensional regulation to three angle mirrors in the K mirror.Three angle mirrors placed regulating device as shown in Figure 2 in the past, and 8 screws are adopted in the adjusting of this device, and 4 are drawn, and adjusting to three angle mirrors is realized with this in 4 tops.This regulating device is in operation, can cause that three angle mirror matrixes are stressed and produce face deformationization, and the light school cycle is very long.
Summary of the invention
For the problem that exists in the regulating device before solving, it is stressed to the objective of the invention is to propose a kind of mirror body of avoiding, and improves degree of regulation, also shortens the used three-dimensional regulating mechanism of three angle mirrors in light school cycle simultaneously greatly.
Three-dimensional regulating mechanism of the present invention comprises: inner ring, outer ring, adjusted frame, three angle mirror fixed mounts, lock-screw, adjusting bolt and adjustment cam.It is characterized in that: inner ring 1 places outer ring 2, and by its radially rotation axis flexible connection, an end of rotation axis is a stationary shaft 4 between outer ring and the inner ring, the other end is threaded screw mandrel left and right adjusting bolt 5, regulate bolt 5 by rotating, can make inner ring is basic move left and right with the outer ring, stroke 1mm.
At the side of outer ring left and right adjusting bolt 5, be provided with the pitching cam 6 of a threaded screw mandrel, cam cooperates with mounting hole on the inner ring, drives pitching cam 6 by rotating threaded screw rod, and can make inner ring is that pitch regulation is carried out on the basis with the outer ring, and stroke is 1 degree.
Adjusted frame 7 is fixed on plane on the inner ring 1, three angle mirror fixed mounts 8 are located in the inner ring, the center pit that threaded screw mandrel up-down adjustment bolt 9 passes adjusted frame 7 successively is connected with three angle mirror fixed mounts 8, three angle mirrors 10 are fixed on the three angle mirror fixed mounts, regulate bolt 9 by rotating, can make the above adjusting bracket of three angle mirrors is that the basis moves up and down.Adjusting bolt 9 sides at the adjusted frame, be provided with the adjusting driftage cam 11 of a threaded screw mandrel, cam 11 cooperates with mounting hole on the three angle mirror fixed mounts, drive driftage cam 11 by rotating threaded screw rod, can make the above adjusting bracket of three angle mirror fixed mounts is that yaw adjustment is carried out on the basis, and stroke is 1 degree.
Stationary shaft 4, left and right adjusting bolt 5, pitching cam 6, up-down adjustment bolt 9 and driftage cam 11 all are furnished with and its lock-screw 3 that is vertical placement, be used for light path regulate finish after, total is fixed.
Advantage of the present invention is:
1. by regulating left and right adjusting bolt, pitch regulation cam, up-down adjustment bolt, yaw adjustment cam, realize the locus correction of three angle mirrors in system, and after adjusting is finished, total is fixed degree of regulation height, good stability with lock-screw.
2. can avoid regulating the minute surface stress deformation that operation causes.
3. adjusting bolt of the present invention is vertical placement with lock-screw, can not influence the adjusting result during locking.
