[0002] Laser communication is a communication method that uses laser as a carrier. It uses light waves as information carriers and realizes communication through the transmission of lasers in optical fibers or the atmosphere. Compared with traditional communication methods, laser communication has the advantages of high transmission rate, strong anti-interference ability, and long transmission distance. The laser communication drive mechanism is a mechanical device used to control laser communication equipment. It is usually composed of a series of precision mechanical parts, such as reflectors, lenses, beam controllers, etc., which are used to realize the functions of laser signal emission, reflection, focusing and deflection;
