Starting with Smith (2008) and The Uses of a Polarimetric Camera; then continuing with Mike Eyler (2009) Polarimetric Imaging For The Detection Of Disturbed Surfaces, we worked with the Salsa Camera from Bossa Nova Tech - a design using an electronically rotating LCD polarization filter. Following a suggestion by an international student from Scandianavia, we considered the possibility that disturbed snow might show interesting polarization signature. David West (2010) showed not so much, which was consistent with the Umov effect I suppose.
We never quite saw the results we were after, and eventually acquired a different design from Flux Data, which uses a beam splitter behind the lens, and three different focal planes to acquire polarization signatures. Jarrad Smoke (2017), compared the two (Comparison Of Polarimetric Cameras), and found that the phenomenology was really quite similar, thought the time aliasing artifacts of the Salsa design were eliminated.
Scott Tyo and I did some work in other areas (2003) - here just as a reference, some review articles by him.
