摘要：
Through controlling wavefront, liquid crystal optical phase array can realize precise and arbitrary angle beam steering within a certain field of view. Beam steering methods based on mutiaperture interference and stochastic parallel gradient descent algorithm are studied. By numerical simulating these two methods, beam can point to the target in far field. Pointing accuracy and steering efficiency have been compared and analyzed. A novel beam steering method is presented, which can improve beam pointing accuracy and beam steering efficiency in total range of beam steering.
