Title The Design of Binary Diffractive Microlens

Abstract Basic theory of Diffractive Micro-optics is introduced,The theory of scalar diffraction and model of the Fresnel diffraction integral are stated, based on which the basic principles of diffractive microlens are investigated, focusing properties of microlens are analyzed. On the basis of the scalar diffractive theory and Fresnel diffraction integral model, a design method of optimize the phase structure according to the diffraction efficiency is analyzed.The design of the principle and the algorithm are analyzed at the same time.By comparing the characteristics of the commonly used optimization algorithms, the genetic algorithm (GA) is applied to optimize the design.The phase distribution of microlens is optimized by genetic algorithm toolbox in Matlab，and the simulation based on Matlab is also applied to analyse the optimization results.
