摘要

The radiation spectrum from a scene is split according to two wavelength regions to provide two spaced images of the same scene, each from the radiation of a different one of said regions, on the cathode of an image intensifier tube. The images are intensified by means of a desired number of image intensifier tubes and the images thus produced on the anode of the last tube are recombined each in an added different color.
