Abstract: A method and apparatus for real-time polarization difference imaging (PDI) video including an imaging lens focusing the light on to a collimating lens, whereby the stimulus beams becomes parallel before striking a polarizing beam-splitter. Segregated orthogonally polarized components of the stimulus are then focused on imaging sensors, and one sensor's output signal is subtracted from the other, thereby creating a real-time polarization difference video image. The efficiency of such a system is greatly enhanced by illuminating the target with a polarized light source (with a polarization orientation matching one of those used in the PDI process), and PDI-enhanced targets can be constructed with surface features and textures optimised to result in a maximum return signal strength and spatial contrast.

Abstract: A polarization filter utilizing Brewster's angle. The polarization filter includes a stimulus receiving body having more than one facet. At least two of the more than one facet being arranged at Brewster's angle (relative to the plane of polarization of the incident stimulus) and positioned in different radial orientations (relative to the incident stimulus) which are adapted to provide differential transmission or reflection of polarized electro-magnetic radiation coming from a common source.

Abstract: A method for polarmetric analysis of scattering media. A first step involves directing stimulus from a linearly polarized stimulus source at a sample. A second step involves directing the stimulus coming from the sample through a collimating system into a polarization segregation unit which causes the stimulus to be segregated into a linearly polarized unscattered component and a depolarized scattered component. A third step involves quantification of scattering processes through computationally comparing the unscattered component and the scattered component.
