Multispectral imaging system

Abstract

Abstract A SYSTEM IS DISCLOSED FOR PRODUCING MULTIPLE IMAGES OF A SCENE WHERE THE IMAGE IS VIEWED FROM A SINGLE OPTICAL SYSTEM AND CONVERTED TO SEPARATE DISPLAYS AT DIFFERENT LIGHT WAVELENGTHS. ALL THE IMAGES ARE PRODUCED SIMULTANEOUSLY. THE EMBODIMENT DISCOLSED INCLUDES A MICHELSON INTERFEROMETER WHICH TRANSMITS THE LIGHT INTENSITY TO A MOSAIC OF INDEPENDENT LIGHT DETECTORS. THE DETECTORS ARE INDEPENDENTLY COUPLED TO AN ANALOG TO DIGITAL CONVERTER WHICH DIGITIZES THE ELECTRICAL RESPONSE OF THE DETECTORS. THE DIGITAL SIGNALS ARE PROCESSED IN A FOURIER TRANSFORM UNIT TO PROVIDE SIGNALS AS A FUNCTION OF WAVELENGTH. THE SIGNALS FROM THE UNIT ARE STORED IN A MEMORY UNIT AND SELECTED BBY A SCANNER UNIT AS A FUNCTION OF WAVELENGTH AND THE INCERMENT OF THE DETECTOR MOSAIC AND APPLIED TO A DISPLAY DEVICE. BY VIRTUE OF THE WAVELENGTH SELECTION, DIFFERENT DISPLAY DEVICES ARE OPERATED AT DIFFERENT WAVELENGTHS TO DISPLAY THE IMAGE AST THE SELECTED WAVELENGTH.
