摘　　要：本文基于标量衍射理论，建立了简明的对准误差与二元光学器件衍射效率的分析模型，得到了适用于一般位相分布器件的衍射效率的简便实用的计算公式。模拟计算表明该模型的计算结果与实际对准误差对器件衍射效率的影响情况相吻合。Based on the theory of scalar diffraction, an error model is established to investigate the effect of alignment error on the efficiency of binary optics elements. Simple formulas of the relationship between alignment error and diffraction efficiency are obtained. Theoretical results along with simulation results are presented and discussed.
