Embodiment 1
[0029] Embodiment 1, a high-precision and stable pendulum mirror device suitable for space environments, Picture 1-1 , Figure 1-2 It is an overall structure diagram of the present invention, which is an overall structure system scheme. It consists of two subsystems, the high-precision adjustment system of the swing mirror and the real-time feedback system of the swing mirror position.
[0030] There are two working modes of the oscillating mirror, one is that the oscillating mirror scans and aligns and maintains two states after alignment;
[0031] When the swing mirror is scanned and aligned, the upper and lower symmetrical flexible structural parts 12 act as the rotation axis, and the piezoelectric ceramic actuator 11 drives the swing mirror chamber 5 and the swing mirror 3 to deflect through the adjustment lever 13. Search, stop scanning when scanning to the working position of the swing mirror, and the high-precision sensor records the working position.
[0032] When ...
