Abstract
In a combination of a focusing optics for imaging a scene onto an image intensifier and means as an ocular for perceiving the intensified image of the scene, a system of input filters obtains color separation in multiplex for feeding to a sole image intensifier. The multiplexed color separated intensified images are joined into a color image. In a system with time multiplexing, a filter disc on the input side rotates in common with another filter disc on the output side. In another system with space multiplexing, the color separated images are obtained by beam splitting side by side on the input surface of the image intensifier and are then combined either with analogous means (filters and reverse beam splitter) or with TV methods.
