ADAPTIVE MULTISPECTRAL IMAGING

A method for multispectral imaging that includes positioning a continuously graded color filter in front of a plurality of detectors. Wavelengths of energy passed by the filter vary smoothly along the filter length and the detectors are configured in a pattern having a plurality of rows each having a plurality of detectors. Each of the plurality of rows is oriented across the length of the filter. The method also includes measuring outputs of the detectors in response to moving an image along the length of the filter and generating a spectrum response function for the image based on the outputs of two or more rows of the detectors using a time delayed integration method.
