Abstract
A multispectral imaging sensor includes at least one superpixel including a plurality of pixels. Each pixel includes an imaging element, and each imaging element includes at least one photodetector. Each pixel further includes a spectral filter associated with the imaging element. The spectral filter permits light to pass to its associated imaging element only within a plurality of passbands.
