A polarization viewer comprising a mechanism for forming a broadview image having a spectral width greater than 2 angstroms and 0.50.degree. based on polarization information of a scene. The polarization viewer is also comprised of a mechanism 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 disposed such that electromagnetic radiation entering the camera mechanism passes through the polarizer analyzer. 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 analyzer first passes through the steering mechanism. The steering mechanism preferably includes a first twist crystal and at least a second twist crystal aligned with the first twist crystal such that radiation passing through the first crystal then passes through the second crystal. Each crystal has a first state and a second state. The first state does not effect the polarization plane of the radiation as the radiation passes through the crystal. The second state rotates the polarization plane of the radiation as the radiation passes through the crystal.
