摘要
基于液晶空间光调制器,探索了傅里叶全息成像及偏振光场调控的新方法。实验包括Matlab GUI仿真和光路搭建测试两部分,通过可视化界面设计参数并模拟计算全息图,再利用单个空间光调制器加载全息图,有选择性地针对入射光的偏振方向调控光波相位。结合光场的矢量特性,从理论和实验探索了傅里叶全息成像原理以及不同入射光偏振化方向下的全息成像规律,从而实现偏振复用的特殊全息光学成像功能。相较于传统的光学全息成像实验,这一基于空间光调制器的偏振全息成像系统具有结构简单、操作方便和成像速度快的优点。
Based on the liquid crystal spatial light modulator, a new method to realize Fourier holographic imaging and control of polarized light field is explored. The experiment includes two parts: Matlab GUI simulation and optical setup construction. The parameters are designed by visual interface and the hologram is calculated, and then the hologram is loaded through a single spatial light modulator to selectively control the light wave phase according to the polarization direction of the incident light. Combined with the vector characteristics of the light field, the Fourier holography imaging principle and holography imaging rules under different polarization directions of incident light are studied from both theoretical and experimental aspects., thereby realizing the special holographic optical imaging function of polarization multiplexing. Compared with the traditional optical holography experiment, this polarization holographic imaging system based on spatial light modulator has the advantages of simple structure, convenient operation and fast imaging speed.
