ABSTRACT:
A transmitter and remotely located receiver are used to form an optical color communication system wherein diffraction gratings blazed, for example, in the sixth and higher dispersive orders are utilized in the transmitter and receiver to provide for simultaneous transmission and reception of color coded information over hundreds to thousands of communication channels. Another receiver embodiment that can be used with the transmitter additionally includes a prism and image intensifier which are utilized to record the color coded information on black and white film in the form of separated grey toned strips. A black and white to color printer is used to convert and print the grey toned strips in original and unseparated color form.
