The analysis of major parameters in short distance fully optical acquisition of ground laser communication

摘要

This paper indicates a fully optical acquisition way which can build up linkage of ground laser communication in short distance, depicts the configuration and function process of acquisition system and discusses important parameters of acquisition process: communication distance, beam divergence angularity, the relation of acquisition time and maximum scan velocity. As a result, 5Km communication distance can be achieved; acquisition time is less than 100s, when horizontal beam divergence angularity is higher than 1mrad.
