摘　　要：依据集成照相术(IP)和计算机图形学原理,提出了一种新的单波长激光在同一种记录介质上一次曝光记录虚拟三维物体的彩色全息图的方法。首先利用计算机图像处理技术对彩色虚拟三维物体进行三原色分解,并对分色后的三维物体进行坐标变换,模拟全息集成照相过程计算获取具有水平视差的三原色体视图序列,再利用彩虹全息术的狭缝进行消除色串扰,实现单波长激光一次曝光记录彩色全息图。理论上分析了该方法的可行性,并进行了实验验证,讨论了影响全息图再现像分辨率的因素。Based on integral photography and computer graphics,a new method for recording color holograms of virtual 3D objects using single wavelength laser is proposed.Three horizontal parallax only integral photography（IP） images whose colors correspond to tricolor are calculated by simulating integral photography.IP images are illuminated with the coherent beam from the opposite side.Three images of the virtual 3D object are reconstructed and overlapped on a particular image plane by three liner micro-lens arrays.With interfering the reconstructed 3D images and the reference beam after a single exposure,a color hologram is created.Experimental implementation of the new method for a simple case is presented.
