The Adaptive Optics Technique for Atmospheric Turbulence in Laser Communication System

This paper states how adaptive optics technique can be used in space laser communication system to compensate atmospheric turbulence when laser beam transmission through it.The core content of adaptive optics is correct laser beam wavefront disturbance in real-time,with it to enhance optical system imaging quality and the next aim is reach the level of diffraction limitation.Adaptive optics system consists of wavefront detection,wavefront control and wavefront correction.The problem of bandwidth matching between time domain and space domain is analyzed detailed.In conclusion,space laser communication and adaptive optics system are all complicated system engineering.If adaptive optics technique can be ap-plied in space laser communication system and is proved by practice,it must be a new milestone in the development of space laser communication
