A Two-Color Input, Two-Color Output Image Intensifier Panel

The design and construction of a two-color input, two-color output image intensifier panel are described. The solidstate panel is so constructed that it can be independently excited by either a visible image or a near-infrared image on the input. The visible input image excites one of the colors in the output image while the infrared input image excites the other color of the output image. The characteristics of the panels are given in terms of input and output light levels, spectral response and gain. Photographs are given which show the output image for visible input only, infrared only, and the two combined.
