Abstract
An imaging device includes a detector array and an aperture disposed along an optical path, with an array of filter elements disposed in the optical path therebetween. The detector array has a plurality of detector elements that are sensitive to a wavelength spectrum of interest, such as, for example, the visible spectrum and/or the infrared (IR) spectrum. Each filter element is configured to filter out energy within the wavelength spectrum of interest that is in a wavelength band of interest to form filtered energy within the wavelength spectrum of interest that is outside the wavelength band of interest. The filtered energy is passed by each filter to at least one corresponding detector element, which generates one or more detector values based on the received energy. The detector values may be processed to determine an intensity value for the wavelength band of interest.
