Description

technical field [0001] The invention belongs to the technical field of fast control mirrors, and more specifically relates to a fast reflection mirror system based on an eddy current sensor which can be applied in a transmissive manner. Background technique [0002] The fast control mirror is an important component that works between the light source or receiver and the target to adjust and stabilize the boresight or beam pointing of the optical system. It has the advantages of small size, compact structure, high precision and high bandwidth, and has been widely used. It is used in important fields such as space laser communication, astronomical telescopes, optical stabilization, boresight stabilization, precise capture, aiming and tracking, deep space exploration, high-precision laser processing equipment and carrier laser systems. [0003] Since the fast mirror system is mainly used in the optical path, in the field of optical detection, it is often necessary to set up a s...

Problems solved by technology

[0004] The traditional fast mirror system uses the optical path sensor to collect position information, but the optical path sensor itself needs to be sensitive to the position change information of the external working mirror body, and is often arranged behind the working mirror body, which affects the transmission function of the working mirror body

[0005] Similarly, the traditional shafting components arranged around are heavy, frictional, and bulky, which has a huge impact on the response bandwidth of the fast mirror

It is impossible to arrange a fast mirror system with high response frequency, small size and easy maintenance in such a compact large system optical path design environment
