两种离子交换型变折射率微透镜

Two gradient-index microlenses made by ion exchange method

分别求得制作自聚焦平面微透镜的开孔式和掩盘式离子交换的相应扩散方程的解,导出掩盘式微透镜的最佳折射率分布,给出微透镜的成像矩阵,制得掩盘式平面微透镜阵列并给出其成像照片及基本参数.

The solution of the diffusion equations for window and disc mask problems are found in fabricating planar miorolenses and the optimum refractive index distribution for disc-mask miorolens is derived. The image matrix of miorolens is given in the paper. We fabracated the disc-mask miorolens array and the parameters and the picture photoed by the array are presented.
