ABSTRACT:
A color image intensifier device includes an evacuated envelope with an input window for receiving incident light from the environment. A photocathode is deposited upon the interior surface of the envelope of the input window for converting the incident light into a photoelectron signal. A phosphor layer, emitting several wavelengths approximating white light when struck by and amplified by an intensified photoelectron signal, is deposited upon an interior surface of the envelope proximate an output window to convert the amplified signal into a visible light output image projected from the intensifier.
