A LABORATORY FLYING SPOT SCANNER FOR VIDEO GENERATION,
Abstract
The flying spot scanner consists of the following elements: a cathode ray tube with the beam deflected in a line or raster pattern; a lens system to focus the image on the face of the CRT on a glass photographic transparency which can be accurately positioned and made to translate at a uniform rate in one coordinate by a motor drive. A lens system focuses light passing through the photographic transparency onto the photo sensitive surface of a photo-multiplier tube to provide a video output signal as a function of time which represents the transparency function of the photographic slide.
