Abstract
Apparatus for continuously reading out the graphic information represented by a charge pattern on a dielectric film includes an integrated circuit array of field effect devices each having a source and drain in series with a respective p-n junction photodiodes. A bias voltage is connected across the field effect devices and respective photodiodes and a load impedance. A scanner positioned to scan a spot of light over the array of photodiodes causes conduction of currents through field effect devices which are rendered conductive by charges on the dielectric film to produce a video signal across the load impedance.
