CRT DISPLAY OF A MOTION PICTURE FILM

摘要: The light spot of a flying scanner is directed upon scanned frame motion picture film which transported at desired rate through the scanning field scanner. deflected in response to horizontal and vertical deflection voltages provided voltage proportional beam cathode ray tube whereon viewing raster traced. by summing amplifier has one input connected signal other output an integrator circuit provides displacement integral rate. In signals, traces shifted compensate for frame. Disposed receive emanating from photomultiplier video tube, thereby displaying thereon. being greater or equal representative leaving during retrace raster, reset provide succeeding field.
