High-precision and high-stability pendulum mirror device suitable for space environment and working method thereof

Abstract

The invention provides a high-precision and high-stability pendulum mirror device suitable for space environment and a working method thereof. A pendulum mirror is arranged in a pendulum mirror chamber. The front section of the pendulum mirror chamber is mounted on a fixed front panel through two flexible structures in an up-down symmetry manner, and no impact force guarantees adjustment stability; the back end of the pendulum mirror chamber is provided with an adjusting rod, and the other end of the adjusting rod is equipped with an adjustment actuator, so that the position of the pendulum mirror can be adjusted precisely; the side surface of the pendulum mirror chamber is equipped with a high-precision sensor; and the high-precision sensor and a sensor connection plate, together with thetwo flexible structure members, the pendulum mirror chamber, the adjustment actuator and the adjustment lever, form real time closed-loop control. The device can ensure coincidence of the adjusting centers of the flexible structures and ensure direction adjusting accuracy and stability to the maximum extent; the high-precision sensor can detect the position information of the pendulum mirror in real time; the position of the pendulum mirror drifts a little bit due to load excitation of temperature and vibration and the like during working; and through the high-precision sensor, position information is fed back and through the adjustment actuator, the position of the pendulum mirror is corrected, thereby ensuring position precision of the pendulum mirror.

Description

technical field [0001] The invention relates to a mirror swing mechanism and device. It involves technical fields such as aerospace, aviation, astronomical terminal instruments, optical detection, etc., especially relates to an ultra-high resolution and stable swing mirror adjustment mechanism and device suitable for use in vacuum or space environments, and more specifically relates to a gravitational Optical path scanning and automatic alignment swing mirror device during space docking of wave telescope. The invention also relates to the method of operation of such a device. Background technique [0002] In 1916, Einstein published his general theory of relativity, which theoretically predicted the existence of gravitational waves. In Einstein's general theory of relativity, space-time geometry is not just the background of physical motion, it has its own dynamic connotation, describing the gravitational field produced by the gravitational source.
