Advanced optical system design

Motion picture film, as a major source of program material for television, is transferred to the video domain using a telecine. A high performance CCD telecine, operating at real time frame rates, has been developed for high definition television. The optical system for this telecine utilizes a feedback stabilized xenon arc lamp, pre-gate optical and spectral signal balancing, a diffuse illumination system, an apochromatic projection lens, a full resolution CCD luminance sensor, and a half resolution RGB trilinear CCD sensor.
