The 1964 publication by Emmett Leith and Juris Upatnieks [J. Opt. Soc. Am. 54, 1295 (1964)] introduced the possibility of using holograms to record three-dimensional (3D) objects. Since then, there has been an interest in creating display holograms, i.e., holograms primarily produced to show objects in 3D. More recently, full color holography has become a reality, which was predicted in the 1964 paper. To record a hologram in which both the 3D shape and the color of the object are accurately reproduced, at least three laser wavelengths are needed. By computer simulation of the holographic color rendering process, the required amount of laser wavelengths and their distribution within the visible electromagnetic spectrum have been investigated. The quality of a color hologram also depends on the properties of the recording material. The demand on a panchromatic material for color holography is described. Recording techniques for color holograms are presented as well as the future of color holography as the perfect 3D imaging technique.
埃米特·利斯（Emmett Leith）和尤里斯·乌帕特尼克斯（Juris Upatnieks）于1964年发表的论文[《美国光学学会杂志》54, 1295 (1964)]提出了利用全息图记录三维（3D）物体的可能性。从那时起，人们就对制作显示全息图产生了兴趣，即主要用于以三维形式展示物体的全息图。最近，全彩色全息术已成为现实，这在1964年的论文中就已被预测到。为了记录能够精确再现物体三维形状和颜色的全息图，至少需要三种激光波长。通过对全息彩色渲染过程的计算机模拟，研究了所需激光波长的数量及其在可见电磁光谱中的分布。彩色全息图的质量还取决于记录材料的特性。描述了对用于彩色全息术的全色材料的要求。介绍了彩色全息图的记录技术以及彩色全息术作为完美三维成像技术的未来发展。
