Abstract

An InGaAs Image Intensifier (“I2”) Camera (C) detects and forms an image (310) to be viewed. An InGaAs photocathode Image Intensifier (312) is used to pass an amplified signal (316) from a screen (320). The InGaAs image intensification tube (312) is optically coupled (328) to an imaging device (322) for passing output light. The output light (316) from the InGaAs tube (312) is transformed by an electronic circuit (322) producing a desired signal output (324). The signal output (324) from the electronic circuit (322) may be further enhanced into an enhanced signal output (310). The enhanced signal output may be formatted into a form for viewing or may be saved.
