Liquid crystal optical phased array multiple-beam forming methods

Three novel multiple-beam forming methods were proposed in this paper for liquid crystal optical phased array. These three methods called sub-aperture method, array division multiplexing method, iterative Fourier transform pattern approximation method could form multiple beams simultaneously for multi-target tracking in lidar and uninterrupted communication among multiple satellites. Principles of these methods were discussed in this paper. Simulations and experiment results were given to verify the feasibility of these methods.
