We compare conventional intensity imaging against different modes of polarimetric imaging by evaluating the image contrast of images taken in a controlled foggy environment. A small-scale fog chamber has been designed and constructed to create the ne

Currently, in CD6, a new line of research devoted to polarimetric imaging is being developed. The use of polarization adds new information that is not reachable using other conventional imaging modes. In addition, recent literature explores the capab
