Abstract
The method of, and apparatus for, producing an electrical video signal representing a charge pattern on an insulating dielectric sheet or film, without destroying the charge pattern, including the steps of: placing a transparent electrode on the free top surface of the dielectric film, placing the dielectric film having the charge pattern in close contact with the free top surface of an uncharged photoconductor having a back electrode connected to a load impedance, and scanning the photoconductor through said transparent electrode and said dielectric film with a flying spot of light to produce a video electrical signal across the load impedance during the scanning.
