Abstract
Multispectral imaging systems are disclosed. An exemplary multispectral imager includes a narrow-band absorptive filter array and a sensor array comprising a plurality of pixels. The narrow-band absorptive filter array has a plurality of filter elements, each filter element being associated with a pixel of the sensor array. The filter elements are organized into groups of N filter elements, where N is greater than three. Each filter element absorbs one narrow band and transmits N−1 narrow bands. The group of N filter elements absorbs all N narrow bands.
