Abstract
A cascaded image intensifier device is presented. In one embodiment the device comprises: at least two sections in cascade, each of a first section and a last section out of the at least two sections including a photocathode unit adapted to convert photons to electrons and a screen unit adapted to convert electrons to photons; wherein the first section includes a reducing element adapted to: (i) reduce ion-caused degradation of a photocathode unit of the first section, and (ii) reduce a number of photons exiting from the first section from a first value to a second value; and wherein the last section outputs a number of photons that equals or exceeds the first value. Also disclosed are methods and systems using the disclosed cascaded image intensifier device.
