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 canproduce a clearer and brighter achromatic aberration stereoscopic color image.
