Claim Text:
1. A method for determining a polarization of a scene, comprising: (a) placing a linear polarizing filter in a field of view of a camera comprising a lens and an array of sensors; (b) successively locating the camera and the linear polarizing filter in proximity to a single position, but at three different orientations for each of which a particular point in a scene is within the field of view of the camera; (c) capturing first through third filtered images while the camera and the linear polarizing filter are at the three different orientations respectively; (d) transferring first through third sets of imaging data respectively representing the first through third filtered images from the camera to a computer system; and (e) computing a polarization of at least said particular point in the scene from the first through third sets of imaging data.
