计算全息图的球面重现

该文研究重现于球面的计算全息图(CGH)的生成和重现。当用平面波照射傅里叶全息图时,所重现的图像一般显示在平面上。该文利用坐标变换方法实现显示于球面的二维图像的计算全息图的生成,并由所生成全息图得到原始图像,从而实现整个全息记录和重现过程的计算机模拟。二维图像重现于球面实际上产生了三维显示,因此该文所提到的方法在从计算全息图重现三维图像方面起到了重要的作用。

Spherical Surface Reconstruction of Computer Generated Hologram

This paper researches the generation and reconstruction of Computer-generated hologram(CGH)which displays on spherical surface.Usually the reconstructed image is located on a planar plane when the Fourier hologram is illumi-nated by a plane wave.In this paper,we realize the generation of Computer-generated hologram of2-D image which displays on spherical surface using coordinate transformation method and then reconstruct the original image from gen-erated CGH,therefore,realize the computer simulation of holographic record and reconstruct process.As reconstruction of a2-D image on a spherical surface actually creates a three dimensional(3-D)displays,this technique may play an im-portant role in attempts at reconstruction of3-D images from CGH's.
