Abstract

There is evidence that polarimetric contrast differences in images are band-dependent. Some previous evidence is reviewed. We fabricated and tested a hyperspectral imaging polarimeter that we reported previously. This device uses a tunable liquid crystal filter and a 16-bit camera. The polarimeter is designed to work in the visible and in the near IR spectral region. We present here some examples of imagery collected with this senor, and show how this data may be used to provide superior target discrimination if used selectively, with the appropriate algorithms.
