摘要: 设计并搭建了基于空间光调制器的相移数字全息实验装置，用计算机控制空间光调制器产生实验所需物体，并且控制相关物体参量，完成了基于空间光调制器的透射式数字物体的全息记录和数字再现．实验结果表明相移数字全息方法优于一般数字全息，基于空间光调制器的相移数字全息方法具有物体数字化、物体参量可调、可实现动态物体等显著特点，为相移数字全息提供了更广阔的应用前景．Abstract: An experiment system of phase-shifting digital holography was designed which uses the digital object produced and controlled by spatial light modulator (SLM) in light path of phase-shifting digital holography; and the records of digital holograms of digital object displayed on SLM and the reconstruction from digital holograms were realized. Experiment results reveal that the phase-shifting digital holography is better than the digital holography, and the phase-shifting digital holography based on SLM will open more space for the phase-sifting digital holography in future, because it has many characteristics such as digital objects, variable parameters, moving objects, etc.
