摘　　要：用三色光栅照相机拍摄景物的两张视差照片,然后用单色激光器经二次曝光全息记录制成一张真彩色体视全息图,在普通白炽灯照明下可再现真彩色体视全息像.该方法制作过程更简单,减少了散斑噪音,消除了彩色全息像的色差,得到的全息像清晰明亮,色彩真实,立体感强.Two parallactic films of a nature color scene are obtained with a three color grating camera. With the films, a true color holographic stereogram can be made with one-wavelength laser through two exposure recordings. A true color stereoscopic scene image can be reconstructed from the hologram as it is illuminated by a white light source. Compared with other methods, this method is simpler in operation. It decreases the scattering noise and gets rid of chromatic aberration of the reconstructed image. It can produce a clearer and brighter achromatic aberration stereoscopic color image.
