Abstract

In order to improve the color effect and the visual angle of hologram,based on the method of mirror images,a new technique is proposed to obtain a real color hologram with a large viewing angle by the combination of computer-generated hologram and optical hologram.There are two steps to realize the method:Firstly,computer-generated hologram H1r,H1g,H1bis yielded with three image objects.Secondly,a rainbow hologram H2is generated by optical ways.In terms of the reversibility of light path principle,an image with a wide viewing angle is reconstructed by reversing the reconstructed wave.The technique achieves a color reconstruction image with a wide viewing angle of 14°.The color effect and the stereoscopic effect of the reconstruction image is increased.

一种制作宽视角真彩色彩虹全息图的新方法

为了提高全息图的色彩效果和视角，在镜像方法的基础上，提出了将计算机生成的全息图与光学全息图相结合，获得大视角的真实彩色全息图的新技术。该方法的实现分为两步:首先，用三个像标的生成计算机生成的全息图H1r,H1g,H1bis。其次，利用光学方法生成彩虹全息图h2s。根据光路可逆性原理，通过对重构波进行反转，重构出具有宽视角的像。该技术实现了14°宽视角的彩色重建图像。增强了重建图像的色彩效果和立体感。

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".
