A polarization viewer comprising a mechanism (12, 18, 20) for forming a broadview image having a spectral width greater than 2 angstroms and 50 DEG based on polarization information of a scene. The polarization viewer is also comprised of a mechanism (12, 18, 20) for providing polarization information to the forming mechanism. The providing mechanism is in communication with the forming mechanism. In a first embodiment, the providing mechanism includes a camera mechanism in communication with the forming mechanism. The camera mechanism includes a fixed polarizer analyzer (12) disposed such that electromagnetic radiation entering the camera mechanism passes through the polarizer analyzer (12). The providing mechanism can also include a mechanism for steering a polarization plane of the radiation. The steering mechanism is disposed such that radiation passing through the polarizer analyser first passes through the steering mechanism. The steering mechanism preferably includes a first twist crystal (18) and at least a second twist crystal (20) aligned with the first twist crystal such that radiation passing through the first crystal has a first state and a second state. |
