【Abstract】 The beam aligning and tracking is a key technique in Wireless Optical Communication System on account of the use of narrow beam,and the microseism of installing platform will make the spot of the beam departing from the receiver.In this paper three available approaches to solve the problem of beam aligning and tracking have been discussed in detail,those are Divergence,Multi-Apertures,Auto Aligning and Tracking.Based on the analysis of those methods,some significant discussions have been made on how to improve the Auto Aligning and Tracking System.更多还原
