ABSTRACT:
The microchannel plate current of a microchannel plate image intensifier is sensed to generate a pulse train applied to the image intensifier photocathode for gating the image intensifier on and off with an on period proportional to the light impinging thereon. The off periods of the pulse train are sufficiently positive to repair photocathode spot damage.
