Photo telegraphyThe transmission of pictures between two points by means of radio or telegraph. A print is wrapped around a cylinder and scanned by a small spot of light. Reflected light values are transmitted as a stream of signals. They control an exposing light source at the receiving station, which exposes light sensitive material on a similar drum.
