Paper Abstract

The analysis of optical antenna gain for laser communications has been made by some authors in the past years, most of them pay attention to on-axis situation, however, in latter years, laser navigation becomes interested, off-axis situation has been given more considerations, four-quadrant detector is commonly used for TEM00 mode detection. But it is unsatisfactory in the case of the divergent angle exceeding some criterion for large variations of distance detection, especially, it is difficult to make a precise judgement for what is the distortions of the wave front by random disturbance. This paper suggested a method of multi- ring detection to meet such demand.
