用两台相同单反相机按一定距离横向排列,同时拍摄三维景物的体视图对。其彩色负片分别用红、绿、蓝滤色镜及普通放大机分色放大,制成黑白正版。然后,以He-Cd激光器4416nm波长激光为光源,将全息干版划分为红、绿、蓝三个色区,以平行激光为参考光,顺序记录体视图对六个分色正版的狭长菲涅耳全息图。再以平行激光反向再现,于像平面用光刻胶版记录再现像的全息图。经电铸模压,制出了色彩还原好、体视感强的彩虹全息图。实验结果初步说明,这项技术可用于人物、自然景色、花卉、昆虫、浮雕地形图等的彩色立体显示,而且可用于人的立体视觉及色觉的定性检查。
With two identical SLR cameras arranged horizontally at a distance, while shooting three-dimensional scene of the body view pair. The color negatives were red, green and blue filters and ordinary magnifier color separation amplification, made of black and white genuine. Then, the He-Cd laser 441 6nm wavelength laser as the light source, the holographic dry plate is divided into three color areas of red, green and blue, parallel laser as the reference light, sequential recording volume view of the six sub-color genuine Fresnel hologram. And then reverse the parallel laser reproduction, in the image plane with a photoresist version of the reproduced image recorded hologram. The electroformed molded, made a good color reproduction, strong stereovision hologram. The experimental results preliminarily show that this technology can be used for the color stereoscopic display of people, natural scenery, flowers, insects, relief topography and the like, and can be used for the qualitative inspection of human stereoscopic vision and color vision.
