One-dimensional quick reflector, two-dimensional quick reflector and flexible supporting structures thereof

Abstract

The invention discloses a flexible supporting structure comprising at least two flexible supporting units for connecting a reflector with a supporting base. Each of the flexible supporting units includes an upper end block for being connected with one reflector, a lower end block for being connected with the supporting base and two reeds; the two reeds are arranged between the upper end block andthe lower end block in a staggered mode, wherein the center lines of the two reeds coincide; and the upper end block and the lower end block are symmetrically distributed along the center lines of thetwo reeds. The center lines of the reeds of the flexible support units are collinear. Therefore, the flexible supporting structure has a simple structure, the production cost is greatly reduced, andthe flexible supporting structure is convenient to manufacturing. Meanwhile, the weight and the size of the flexible supporting structure are reduced; the rotational inertia of the flexible supportingstructure is reduced; the system power consumption is reduced; and the control bandwidth and the system reliability are improved. In addition, the invention also discloses a one-dimensional quick reflector comprising the flexible support structure and a two-dimensional quick reflector comprising the flexible support structure.

Description

technical field [0001] The invention relates to the technical field of optical precision instruments, and more specifically relates to a flexible support structure. In addition, the present invention also relates to a one-dimensional fast reflection mirror and a two-dimensional fast reflection mirror comprising the above-mentioned flexible support structure. Background technique [0002] The fast reflector can change the incident angle between the incident light axis and the mirror surface by controlling the swing of the reflector, so as to realize the adjustment of the direction of the reflected light axis. As an optical path adjustment technology, the fast mirror system is widely used in laser weapons, laser radar and other technical fields. [0003] In the fast mirror system, the mirror is usually constrained by a flexible support structure. Therefore, the flexible support structure is a key component that affects the swing control accuracy and service life of the fast m...

AI Technical Summary

Problems solved by technology

[0004] The flexible support structure in the prior art needs to have a certain wall thickness to ensure that the rotational stiffness perpendicular to the direction of the rotating shaft is large enough, which is not conducive to the weight reduction of the support structure, and also requires complex incision processing technology. On the one hand, the processing cost is high, and on the other hand On the one hand, complex cuts are also not conducive to adjusting the rotational stiffness
