Abstract : A method that uses a one dimensional array detector to measure the two dimensional wavefront tilt of a beam, is proposed. A preliminary experiment is given to verify the principle. The main limit for a laser guide star adaptive optics system is the focal anisoplanatism. Firstly, based on the filter function of the atmospheric turbulence sensing geometry, the variance of the residual wavefront distortion resulting from focal anisoplanatism was derived, then the effective diameter do of the imaging system was derived. d0 was calculated according to the atmospheric turbulence model in Kunming and Xinglong. The calculation shows that the correction of the piston and tilt is important for the adaptive optics system.
