Arrangement for exposing photosensitive materials with information displayed on the screen of a cathode ray tube

Claim 1

Apparatus for exposing photosensitive material to information displayed on the screen of a cathode ray tube which comprises in combination: a. a cathode ray tube having a screen with information thereon; b. a plurality of coplanar juxtaposed liquid crystal cells, each of said liquid crystal cells comprising two transparent electrodes and a photoconductor layer and a liquid crystal layer interposed therebetween and having means for applying a potential across said electrodes to record information projected thereon; c. an optical system arranged in front of said cathode ray tube whereby said information on said screen can be projected onto said liquid crystal cells; and d. light source means for exposing said photosensitive material to said information stored in said plurality of liquid crystal cells, at least one of said cathode ray tube and said optical system being movable relative to said liquid crystal cells so as to permit selective projection onto each said cell of said information on said screen, and at least one of said light source means, said optical system and said plurality of liquid crystal cells being movable relative to said photosensitive material so as to permit said light source means to expose said photosensitive material to said stored information.
