New 35mm Television Film Scanner

E. H. Traub

New solutions for the film transmission problem for both black-and-white and color are described, comprising (1) nonstorage flying-spot scanning technique, (2) continuous exposure and (3) continuous film motion combined with optical compensation. A new form of optical compensator is then discussed which is both simple and small and which provides the possibility of solutions for film-shrinkage correction and iso-film-transport. The new optical compensator is corrected for various aberrations and has good optical efficiency. A color television film scanner incorporating these features is described.
