摘　　要：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４４１６ｎｍ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。The photographs of 3-D object or scenery were simultaneously taken with identical single reflective cameras arranging side by side in an given space.The magnified black white positive separation plates of the negative color film were made with an ordinary enlarger and the filters of red,green and blue.First of all,the primary Fresnel hologram concluding six narrow holograms of positive separation plates was made with a collimated reference beam.Subsequently,the stereoscopic rainbow color hologram of the reconstructed real image was then recorded on a photoresist plate located in the image plane.The coherent beam used both in the first and the second recording step was He Cd laser in 441.6nm wavelength.The reconstructed images of final embossed holograms were as clear,stereoscopic and colorful as the original.The preliminary experimental results of the successful record of five types of object demonstrate that the above technique can be used in stereoscopic color display of figure,natural scenery,flowers and plants,insects and embossed topograph etc. Besides,it can also be applied to stereopsis and color vision qualitative test.
