ABSTRACT:
An image intensifier device for producing a color output image includes in a proximity focused intensifier tube, an RGB color filter matrix screen printed upon a glass wafer which is laminated to the input faceplate of the tube and sandwiched between the faceplate and the photocathode. The RGB matrix filters incident light into RGB components which are amplified by the tube. The output image is colorized in a first embodiment by passing white light fluorescing from a phosphor layer through an RGB output filter matrix which is functionally aligned in an operating tube with the input matrix. In a second embodiment, a UV emanating phosphor layer excites an RGB matrix of secondary phosphors. In a third embodiment, IR filters are included in the RGB input matrix and a narrow band output filter is assigned to represent IR information in the RGB output matrix. In a fourth embodiment a plurality of RGB phosphors replace the phosphor layer of the previous embodiments and directly fluoresce color information.
