Abstract
A night vision device which applies a time-varying voltage to the photocathode of the device during periods of high average light intensity from a scene being viewed. The purpose of applying this time-varying voltage during periods of high average light intensity is to reduce the average current through the photocathode, thus increasing reliability for the night vision device while preserving image resolution.
