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.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. The record of digital holograms of digital object displayed on SIaM 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.
