摘要

在现有空间光调制器二维图像重建方法的基础上，研究了提高三维图像重建质量的方法。基于衍射理论，分析了有限填充因子的点阵SLM对重建像的影响。通过将双线性相位编码到纯相位全息图中，使有效光远离中心光轴，从而可以完全重建原始图案的细节。通过添加双会聚球面波的相位，可以在空间上分离重构像的两个聚焦面和由SLM晶格结构引起的多阶光束。利用空间滤波器分别消除重构图像中高阶衍射光束和零阶光的影响。为此，设计了基于液晶空间光调制器(LC-SLM)的全息光电显示系统。

Optimization of reconstructed images of 3-D phase hologram based on phase-only spatial light modulator

Based on the existed ways of 2-D reconstructed images by spatial light modulator(SLM),the methods to enhance the reconstructed quality of 3-D images are investigated.Based on the diffraction theory,the effects of a lattice SLM with a limited fill factor on the reconstructed images are analyzed.The effective light is moved away from the center optical axis by coding the double linear phases into the phase-only hologram,so the details of the original patterns can be reconstructed completely.The two focused planes of reconstructed images and the multi-order beams caused by the lattice structure of the SLM can be separated spatially,through adding the phases of doubleconvergent spherical wave.The spatial filter is used to eliminate the influences of higher-orders diffraction beams and zero-order light of reconstructed images,respectively.A holographic optoelectronic display system based on liquid crystal spatial light modulator(LC-SLM) is set up to demonstrate this method.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
