Abstract
An imaging system employs a photoconductive material capable of bearing a latent photostatic image, a plurality of elongated parallel electrodes adjacent the photoconductive material, selective scanning of the individual electrodes to produce charge carriers within the photoconductive material, and time-ordered detection of the current created by the charge carriers in the plurality of elongated parallel electrodes. Dynamic rearrangement of the detection pattern for individual electrodes allows for detection from effective electrodes wider than the individual electrodes. Appropriate addressing of the effective electrodes during the scan produces a pixellated representation of the latent image having selectable resolution and reduction of edge-effect artifacts of known systems.
