In this short video linked below, experimental results show an underwater scene processed via polarization differences between multiple images of the same scene taken through different polarization filters. The polarization differences were recorded onto separate images, and then the images were compared. The comparison resulted in a pixel by pixel correction of the image for backscatter. While the backscatter signal was calculated, the depth information for the pixel was also calculated based on a uniform backscatter model along a line of sight.

The video illustrates the 3D information via rotating the perspective of the image up and down, and highlighting different measured points in the foreground and background. Cool stuff!
