实现控制波前传播的纯相位衍射光学元件的设计
Design of a Phase-Only Diffractive Optical Element for Control of Wave-Front Propagation
摘要
基于投影限制集算法(POCS),设计出用一个纯相位调制的衍射光学元件实现控制光波前在三维区域之内的传播,将输入的高斯光束变换为沿纵向调制的等光强的2×2光束阵列。模拟计算表明,该算法在控制光波前传播方面是有效的。
Abstract
Based on the projection onto constraints sets algorithm, we have designed a phase only diffractive optical element (DOE) for controlling beam propagating in 3 dimensiona region. This DOE transforms the input Gauss beam to 2×2 beam arrays in modulating longitudinal direction. The results of simulated calculating shows the validity of projection onto constraints sets (POCS) in controlling wave front propagating.
