Primary attention has been given to the problem of the generation of background light caused by spontaneous emission and its amplification in passing through an intensifier. Because of the high fluorescence level occurring, schemes for possible lowering this background were considered. One of these involves the incorporation of a non-uniform pumping intensity or the incorporation of a non-uniform density of luminescent states along the amplifier axis. Another possibility considered is the use of an auxiliary abosrbing medium placed between the intensifier output and the observers eye, which would be optically non-linear in such a way that its light transmission is low below a specified light level, but high above this threshold. The factors concerned with the choice of a material for the amplifier itself were separately considered, and the problem of obtaining uniform pumping in the case of an optically-pumped amplifier was also considered.
