Paper Abstract

Laser communication has many outstanding advantages, such as high optical gain, high anti-interception, high anti-interference ability and high communication rate, it is an important technical method to solve the problem of high speed communication. The optical antenna is responsible for the reception and transmission of the signal, which is an important part of the laser communication terminal. Based on the general research situation at home and abroad, from the aspect of system SNR and efficiency, this article has determined some targets such as receiving / emission efficiency, wave aberration and ability of off-axis stray light suppression; combined with specific application requirements, we have determined the basic parameters such as communication wavelength: 1545nm, aperture: 100mm, FOV: 0.1 degrees, optical magnification: 15 times. According to the above parameters, a set of reasonable optical antenna system has been designed and the test equipment is set up to measure, the test results are all satisfied. This paper has some reference value for the design and test of laser communication optical antenna.
