Abstract

This paper describes a method for controlling light level for an intensified focal plane array low light level television camera. Light integrating properties of the image intensifier photocathode, and the focal plane array (FPA) are exploited to control light exposure by time domain control only, gating the intensifier photocathode. Shutter efficiency effects of charge propagation velocity on the photocathode are empirically examined.
