Abstract

The maximum quantum efficiency of ASOS photoconductor is more than two orders of magnitude higher than that of photographic emulsions. The ASOS photoconductor is essentially grainless, its modulation transfer function (MTF) is at least equal to that of the best high-resolution film, and it can store electron densities twenty times greater than the maximum grain density of the best film emulsion. It is not surprising that, for equal resolving power, a far higher sensitivity is expected of high-resolution television systems than is obtainable with photographic cameras.
