Paper Abstract

The purpose of this paper is to describe some of the electron optical techniques developed to achieve state-of-the-art performance in a cathode ray tube-based, ultra-high resolution color film recording system. Proper selection and use of cathode ray tube, deflection yoke, magnetic focus lens, astigmatism correction, centering, and aperture flooding coils will be discussed. Absolute control over the size, shape and position of the scanning electron beam spot is necessary to produce a display capable of yielding over 7500 resolvable points across the CRT face with resulting image content in excess of 31 million picture elements per field. No single factor is responsible for the kind of performance outlined here. Rather, it is the refinement of a combination of disciplines integrating optics, electron optics, analog and digital electronics.
