ABSTRACT:
A color image reproduction system wherein there are recorded in superimposition on an imaging member a plurality of images respectively corresponding to the color content of different colors of an original image. Each recorded image is in the form of a surface deformation phase grating which is at a different angular orientation from the phase grating(s) of the other image(s). In operation, the imaging member is sequentially exposed to an original image through spatial light modulating means with illumination of appropriate color at least two times, in each instance employing illumination of a different color and positioning the spatial light modulating means at a different angular orientation. In a preferred embodiment three exposures of the imaging member are made using red, blue, and green light and there is provided a full color reproduction of a full color original image.
