英文摘要： The principle of network based on multi-point laser communication simultaneous is the key of realizing the world of high-speed information transfer. In view of the people’s livelihood, defense security and demand on exploration and transmission information of space science, this technology has important significance, but there is no mature plan report. This project is aimed at this technical gap, based on the foundation of research work in the field of space laser communication of changchun university of Science and Technology , research on optical principle and APT control method of multi-point laser communication system, establish mathematical model and simulated it by computer. A general scheme of multi-point laser communication system was put forward. The optimization design theory and the adjustment method of the optical system and the key technology of laser capture alignment to overcome tracking control algorithm based on Multi-mirror were studied. Combination theoretical research and simulation analysis and experimental, test scheme of multi-point laser communication system for aerospace in the laboratory was designed to demonstration the principle and key technology. This research will establish an important foundation for the construction of the space information network, which is of great significance
