摘　　要：本文通过对自聚焦平面微透镜折射率分布的实际测量和数学拟合,得到了一个简洁的折射率分布表达式。接着从基本的光线方程出发进行了光线追迹,推导出了描述自聚焦平面微透镜近轴成象特性的公式。文中还对数值孔径和表面凸起效应进行了有益的讨论。In this paper,a simple and clear index expression of pla- nar microlenses is obtained through actually measuring the index dis tribution and mathematically simulating.The index function is the sum of decomposed functions of radial distance and axial distance.By using the basical optical equation,the ray trace is calculated and these equ- ations describing the imaging property of planar microlenses are deri- ved.In this paper,the numerical aperture and the effect of the swelled structure are also discussed.
