This paper demonstrates a method to record a set of twelve ultra-realistic full-color analog holograms presenting the same brightness, transparency and homogeneous colors for the fabrication of a Fantatrope, a dynamic holographic 3D display, without the need for special viewing aids. The method involves the use of 3D printer technology, a single-beam full-color Denisyuk optical setup with three low-power lasers (red, green, and blue) and an iso-panchromatic high-sensitive silver-halide holographic emulsion specially designed for recording analog holograms without any diffusion. A cyclic animation is created with a 3D computer graphics program and different elements are 3D printed to form models for the holograms. Holograms are recorded with a full-color holographic setup and developed using two simple chemical baths. To prevent any emulsion thickness variations, the holograms are sealed with optical glue. Results confirm that all holograms recorded with this protocol present the same characteristics, which allow them to be used in the Fantatrope.
本文展示了一种记录一组十二个超逼真全彩模拟全息图的方法，这些全息图具有相同的亮度、透明度和均匀的颜色，用于制造一种无需特殊观看辅助设备的动态全息3D显示器Fantatrope。该方法涉及使用3D打印技术、带有三个低功率激光器（红色、绿色和蓝色）的单光束全彩丹尼苏克光学装置，以及一种专门设计用于记录无任何扩散的模拟全息图的等全色高灵敏度卤化银全息乳剂。使用3D计算机图形程序创建循环动画，并对不同元素进行3D打印以形成全息图的模型。用全彩全息装置记录全息图，并使用两个简单的化学浴进行显影。为防止乳剂厚度出现任何变化，用光学胶水密封全息图。结果证实，用该方案记录的所有全息图都具有相同的特性，这使得它们可用于Fantatrope。
