Appeal No. 1998-1441
Application No. 08/294,779
medium at least when said at least one scanned light beam is modulated to have
an intensity above said predetermined level is applied to said location, a
corresponding location of said electrooptic medium in registration with said
photoconductive material which has become conductive undergoing a light
transmissive state transition upon application of said electric field modulated to be
at least at said predetermined threshold, whereby said image input by said image
inputting means is stored in said electrooptic medium; and
means for reading said stored image from said light valve means;
wherein said image is written into said electrooptic medium at successive
locations in said light valve means where said predetermined threshold of the
electric field and said predetermined intensity level of the at least one scanned light
beam are simultaneously satisfied, for reading by said image reading means.
