Abstract

The invention discloses a two-dimensional moving magnet type rapid reflector device which comprises a reflector, a rigid supporting assembly, a reflector support, a voice coil motor, a displacement measurement sensor and a shell. The reflector is supported at the front end of the base of the shell by the reflector support; the rigid supporting assembly connects the reflector support to the front end of the base of the shell; the voice coil motor is fixed between the reflector support and the base of the shell; and the displacement measurement sensor is fixed on a base of the shell. According to the invention, the moving magnet type rapid reflector device is adopted, a large rotation angle range is realized, the technical problems of thermal deformation of the reflector and the like causedby cable dragging and coil heating of a moving-coil type design are avoided, and the structure is reasonable and compact in arrangement and convenient to install.

Description

technical field

[0001] The invention relates to the technical field of photoelectric scanning and tracking, in particular to a two-dimensional moving magnet fast mirror device. Background technique

[0002] The fast reflector is a component that works between the light source or receiver and the target to adjust and stabilize the visual axis of the optical system or the beam pointing. By using a voice coil motor to precisely control the deflection direction of the reflector, the beam deflection angle can be precisely controlled. It is used to realize the rapid adjustment of the "deflection-tilt" azimuth angle of the mirror, and can be used in applications such as line-of-sight stabilization or scan compensation in the optoelectronic field. Due to its advantages of compact structure, fast response, high working bandwidth and high pointing accuracy, it is widely used in astronomical telescopes, adaptive optics, image motion compensation, free space optical communication, preci...
