Abstract

A two-dimensional large caliber fast control reflection mirror is suitable for various optical systems to drive and stabilize the light beam. The problem to be solved is that, the requirement of the reflection mirror caliber larger than 250 mm is satisfied driven by a straight-line drive device, the inclination angle range and the resonance frequency of the fast control reflection mirror can be effectively improved and increased. The invention compares four blocks of distributed spring sheets to the central spherical hinge to implement the flexible rotation around the dual shafts of the reflection mirror and rigid fastening of the rest freedom degrees; the light weighting of the rotating body and the minimum of the rotational inertia around the shaft can be implemented by improving the reflection mirror fixing mode, uniting the rotating centers of the dual shafts and the gravity centers of the rotating body and light weighting design of the supporting frame and the reflection mirror; the compact whole structure and the small appearance size can be implemented by reasonable arrangements of the straight-line drive device and the micro-displacement position sensor.

Description

technical field [0001] The invention relates to a reflector structure suitable for astronomical telescopes, laser communication, image stabilization systems, adaptive optics systems, tracking and aiming and laser emission systems. Specifically, it is a two-dimensional mirror structure driven by a linear drive device. Large aperture fast steering mirror structure. Background technique [0002] Fast control mirrors are used in various optical systems to drive and stabilize light beams. As sensitive components, their main properties include tracking range, resonance frequency and effective aperture. The tracking range is the maximum deflection range of the mirror, which determines the range that can be compensated and corrected; the resonance frequency is directly related to the bandwidth and response speed of the control system; the effective aperture is the clear aperture of the mirror, and its size affects the improvement of the structural resonance frequency. At present, t...
