Abstract

The invention discloses a two-dimensional high-speed scanning mirror device, which includes a mirror, a mirror bracket, a voice coil motor, a rotating motor, a rotating bearing assembly and a casing; the mirror is fixed on the The front end of the housing; the rotating motor is fixed at the rear end of the housing through the rotating bearing assembly; the voice coil motor is fixed between the mirror bracket and the rotating motor. The two-dimensional high-speed scanning mirror device of the present invention can achieve a larger range of rotation angles, and at the same time avoid technical problems such as cable dragging in the moving coil design, thermal deformation of the mirror caused by coil heating, and the structure is reasonable and compact , easy to install.

Description

technical field [0001] The invention relates to the technical field of photoelectric scanning and tracking, in particular to a two-dimensional high-speed scanning 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 the applications of lidar and lidar systems, mainly including 3D mapping, aircraft landing, spacecraft doc...
