Piezoelectric ceramic deflecting mirror control system applied to inter-satellite laser communication

The invention discloses a piezoelectric ceramic deflecting mirror control system applied to inter-satellite laser communication, and belongs to the field of laser communication. The device comprises a fine tracking execution mechanism, an in-advance aiming execution mechanism, a signal receiving branch, a laser transmitter, a first spectroscope and a second spectroscope. The formed piezoelectric ceramic deflection mirror control system for inter-satellite laser communication introduces a composite tracking control method under a fine tracking field of view and a nutation field of view for cooperative work, is used for compensating micro vibration of a satellite platform, has the two-dimensional motion characteristics of high scanning speed and high positioning precision in a small-range field of view, and has a wide application prospect. The invention provides a solution for realizing high-precision capturing and tracking of laser signals and efficient and stable single-mode fiber coupling, can realize integr
