Claim One:
1. An optical system comprising: a photodetector array to detect first light of a wavelength within a wavelength band from 300 nm to 1200 nm of a scene, the photodetector array representing the detected first light as first image information; an optical element overlying the photodetector array to focus the first light on the photodetector array; an infrared imaging device for detecting infrared light including some wavelength within an infrared wavelength band from 3 microns to 30 microns of the scene, the infrared imaging device representing the detected infrared light as second image information; a phase grating illuminating a pattern on the infrared imaging device responsive to the infrared light; and at least one processor to combine the first image information representing the first light of the scene detected by the photodetector array with the second image information derived from the infrared light of the scene detected by the infrared imaging device.
