Abstract
A color image reproduction system wherein there are recorded at different angular orientations on a deformation imaging member at least two images corresponding respectively to the color content of at least two different colors of an original multicolor image. Readout illumination provided by an extended light source is converted to a plurality of point sources and deflected to the imaged member by a member comprising a transparent substrate carrying a plurality of mirrored areas. The information- modulated illumination is then reflected to provide a reproduction of the original image at an output image plane.

A color optical reproduction system comprising arranged along an optical path
- an extended light source;
- means for generating a plurality of point light sources;
- means to project images of said point light sources at an image plane;
- means located at the image plane of said point light sources for folding said optical path to direct light from said point sources to a deformation imaging member;
- a deformation imaging member bearing multicolor information, said information comprising at least two images superimposed over each other, said images being in the form of surface deformation phase gratings arranged at different angular orientations and corresponding respectively to the color content of different colors of an original multicolor image;
- and
- light filter means for selectively transmitting to an output image plane the color content of the multicolor original image corresponding to the images recorded by the imaging member, wherein said light filter means and means for folding the optical path are parts of the same integral member.
