Abstract
A photo-optical imaging system suitable for use in an electronradiography system which produces an electrostatic charge image at an electrode. An electrode having a photoconductor layer and a transparent electrical conducting layer, with the charge image at the photoconductor layer. A light beam and various arrangements for scanning the beam over the photoconductor layer through the transparent layer for selectively transferring charge to the electrically conducting layer through the photoconductor layer as portions of the photoconductor layer are illuminated by the beam, and a data storage unit for receiving and storing data corresponding to the magnitude of charge at the photoconductor layer.
