"Research question: Using Polarimetric imaging, what is the capability for the detection of disturbed surfaces (soil, asphalt, other)? In particular, what capabilities are provided by a compact video imaging system currently being acquired by NPS for various research uses? Discussion of topic: Polarimetric imaging is the final domain in optical systems, following along after panchromatic and spectral imaging. This technology is now viable to test for possible phenomenologies and applications of military interest. Since polarization is strongly affected by surface roughness, it is intrinsically sensitive to disturbed surfaces. As such, it should be good for detection of IEDs, and traffic by foot or vehicle. There are some reasons to believe it may help discriminate good and bad landing zones for helicopter activities in desert environments, and may help helicopters to avoid 'brown outs.' Conclusion: There were no significant changes in the area of degree of linear polarization over a fixed amount of time at a fixed target."
