Study of pointing error compensation method of laser spot in atmosphere environment

According to the problem of pointing error of laser spot in atmosphere environment,the laser axis error measuring system is designed.The phenomenon of the deviation between the geometric center and the target center of the laser spot because of the influence of various factors of the atmospheric environment are discussed.A new error compensation method by using digital image processing technologies and barycenter method is proposed,and adequately using laser spot full-court data,the laser spot pointing error is studied theoretically and experimentally.The outfield experimental result shows that the method can make effective compensation to the pointing error.The proposed compensation method is shown to be valuable in engineering.
