分析了基于标量衍射理论的位相型衍射微透镜的光学行为，结合等效媒质理论提出了二元衍射微透镜的一种新的亚波长结构近似设计方法。根据标量理论位相量化的概念，分析连续浮雕透镜的相移函数，结合等效媒质理论的等效折射率表达式，可以确定亚波长结构透镜的面型函数。

The optical behavior of the phase diffractive microlens isanalyzed based on the scalar diffractive theory and the new approximate design method for binary diffractive microlens with subwavelength structure by the effective medium theory is presented. The phase-shift function of continuous surface-relief lens is discussed according to the concept ofquantified phase of scalar theory ,and then the surface function of the lens with subwavelength structures can be determined by the effective refraction expression of the effective medium theory.
