  • Patent number: 7855786
    Abstract: An imaging system has a single focal plane array that does not require the precise alignment of multiple cameras relative to one another. It incorporates a multi-band, band pass filter that includes filter elements corresponding to pixel regions of a detector within a camera. The imaging system may further incorporate a detector that vertically discriminates among radiation in different spectral bands incident on an image plane of the detector. In this manner, spectral content may be determined in each spatial region without the need for beam splitting or multiple cameras. The filter itself may further comprise different filter elements, for example, filter elements A and B arranged in a checkerboard pattern, where filter element A passes different spectral bands than filter element B. In this manner, multi-spectral, high resolution images may be generated using a single camera that significantly improves upon image discrimination as compared to, for example, the Bayer color filter array pattern.
