True Color Holographic Stereogram
真彩色体视全息图

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.
