US Patent 9818193 Spatial resolution enhancement in hyperspectral imaging

In a hyperspectral imaging system and method, a pixilated imaging sensor array receives light reflected from, transmitted through, or scattered by a target scene. Images of the target scene are acquired at a number of times and these images are processed to generate hyperspectral data for each pixel of the imaging sensor array based on data for the pixel included in each of the acquired images. This processing can include spatially aligning two or more of the images that were spatially shifted with respect to each other when acquired based on at least one common image feature in the images.
