Optical image processor

Claim 1

An optical image processor, comprising first and second transparent electrodes, a photoconductive member and a light-modulation member, both of said members being interposed between said electrodes, for forming a charge image according to a first optical image by photoelectric effect in said photoconductive member when illuminated with an electro-magnetic radiation beam for writing said first optical image, and for forming, in accordance with said charge image, a second optical image correlating with said first optical image by light-modulation on said light-modulation member when illuminated with an electro-magnetic radiation beam for reading, in the presence of an electric field, comprising: a plurality of photoconductive segments, provided in said photoconductive member, each having a pillar-like structure extending in an applying direction of said electric field, with a space among said photoconductive segments for forming said charge image when illuminated with said electro-magnetic radiation beam for writing, said photoconductive segments exhibiting a specific level of transmittance to a wavelength of said electromagnetic radiation beam for writing; and a transparent high resistive member provided in said space for preventing transfer of electric charges of said formed charge image among said photoconductive segments, said transparent high resistive member exhibiting a higher level of transmittance than said level of transmitance exhibited by said photoconductive segments to the wavelength of said electro-magnetic radiation beam for writing, wherein said electro-magnetic radiation beam for writing incident to said transparent high resistive member is radiated to said photoconductive segments having a pillar-like structure.
