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.
