Landis, working in the RCA television laboratory, built the first model ever made that proved that the optics of the Schmidt telescope could be modified to project sharp and brightly illuminated television images. Working with E. G. Ramberg and I. G. Maloff, he also constructed the first ultra-speed optical system of this type for theater television projection,1 and the first patent on the adaptation of the Schmidt optics to television use was issued to him.2 Many of the practical problems of optical design and economical construction were later worked out by D. W. Epstein and I. G. Maloff who also applied the Schmidt optics to home receivers.3"5 The theory of reflective optical systems of this type has been extensively discussed elsewhere.6-7 This paper will be restricted to practical aspects of the system 426 November 1951 Journal of the SMPTE Vol. 57
