基于HOE的全息显示双目视差构建方法OA北大核心CSTPCD

Holographic optical element(HOE)is one of the important devices for holographic 3D display.In order to solve the problem of parallax mismatch when HOE is used for binocular holographic display,this paper proposes and implements a holographic display binocular parallax construction method based on HOE.At the same time,the aberrations of the components are analyzed and corrected.By analyzing the production principle and imaging rule of HOE,combining the virtual model rendered by ray tracing technology and the real scene model,a holographic binocular display system based on HOE is designed,and a binocular parallax construction method is proposed,that is,a real-time view image containing binocular parallax relationship is provided for the observer when acquiring the coordinate position of the human eye.By further analyzing the cause and process of image distortion in holographic display system,an optimization algorithm to remove the distortion is proposed.Experiment results show that the proposed method can not only realize the HOE display holographic 3D image in real time,but also solve the problem of parallax mismatch and image distortion in the holographic binocular display of HOE.
