单透镜菲涅尔计算全息显示系统中多级像和零级光的去除
Elimination of zero-order beam and multi-images in single-lens Fresnel holographic display system
摘要
Abstract
In order to eliminate the interference of multi-level images and zero-order beam,a system with single-lens structure is proposed,and a single image without crosstalk is obtained.The Fresnel hologram is obtained by using Gerchberg-Saxton (GS) algorithm.The inclined plane wave phase is pre-superimposed on Fresnel hologram to move the image to a central location.The virtual imaging behind spatial light modulator(SLM) is imaged to the front using imaging lens.At the same time,the spatial filter is placed in the rear of imaging lens,and the multi-level images and zero order light are filtered.The size and position of the reconstructed image can be modified conveniently by adjusting the position of lens and SLM,and the optical system length is shortened.The method utilizing the virtual image provides a new way for calculating holographic display based on liquid crystal SLM.关键词
