Xerographic system employing waveguide addressing and modulating apparatus

Claim 1

An imaging system for producing an image responsive to optical input from an original image, the system comprising: (a) a light sensitive imaging surface; (b) a plurality of individual optical waveguides having light propagating therethrough and impinging said surface, the waveguides being formed from a material which modulates the propagating light responsive to an electric field, (c) a means to modulate the propagating light in the individual waveguides which comprises a common electrode adjacent to the waveguides, a charge-coupled device positioned to intersect the individual waveguides, the charge-coupled device including an individual electrode adjacent each waveguide opposite the common electrode, and a control means to optically scan an original and to cause the charge-coupled device to place a charge at selected ones of the individual electrodes responsive to non-image areas of the original so as to establish an electric field between each of the selected ones of the individual electrodes and the common electrode.
