The invention provides an inter-
satellite laser communication imaging and calibration integrated method and
system. The
system comprises a
primary mirror, a
secondary mirror, a narrow-band filter, an
optical imaging and calibration integrated module, an imaging and calibration control module, a
laser communication transmitting module, a transmitting fast reflecting mirror, a polarizing
beam splitter, a
beam splitter, a receiving fast reflecting mirror and a
laser communication receiving module. The
optical imaging and calibration integrated module performs star imaging and
data processing, and corrects star imaging and calibration; scanning and imaging the uncertain area;
processing to obtain target and background characteristics; and the laser communication terminal performs bidirectional capture locking, starts communication and transmits data. According to the invention, inter-
satellite laser communication, imaging and calibration are integrated, the imaging and calibration time is shortened, the size and weight of the terminal are reduced, visible light image information of a target and a background environment and the
pointing error of a calibration device are obtained, an uncertain capture area of the laser communication terminal is reduced, the laser
communication link establishment speed is improved, and the communication efficiency is improved. And high-speed inter-
satellite laser communication is realized.
