Abstract

Abstract

Research on co-aperture designing methods with which the space imaging optical system can be used as laser transmitting antenna is important to alleviate the load of the satellite and to deal with sudden trouble. First, space laser transmitting design request was analyzed based on the power transferring in laser communication link and the difference between imaging system and laser transmitting system was given. Then three design methods generally used for co-aperture system based on a given imaging optical system were proposed. Their performance were analyzed and compared, and their advantage, disadvantage and fitting areas were given. Finally, the transmitting beam of the designed co-aperture system was simulated, and the imaging and laser communicating experiment were made after system fabricating and aligning. Results show that the least divergence angle of the transmitting beam is about 18.2 μrad which is close to the system diffraction limitation. Besides the transmitting beam is of great quality and the received image is nearly same as the one obtained by the imaging system when observed with the naked eyes. It is approved that the co-aperture design can satisfy the need of space imaging and laser communicating mission well.
