title = "The design method of beam splitting based on DOE and its application in 3D imaging Lidar",
abstract = "In this paper, a factor reflecting the uniformity and the efficiency of grating beam splitting is introduced, moreover the scalar diffraction calculation method combined with the Gerchberg-Saxton iterative algorithm and the simulated annealing algorithm is proposed. Using this method, we iteratively obtain the optimal grating phase distribution by minimizing the factor, and a 16×4 beam splitting DOE with 86.3\% efficiency and 92\% uniformity is designed which has been successfully applied in 3-D imaging Lidar. The design method discussed in this paper provides new ideas for high-precision multi-beam Lidar and has better engineering application value.",
