Claim One:
1. A device for imaging a scene, comprising: (a) a detector, of radiation from the scene, that includes a plurality of detector elements; (b) a circularly variable filter; (c) a mechanism for rotating said circularly variable filter substantially perpendicular to an optical path of said radiation from the scene to said detector; and (d) a data capture apparatus for: (i) repeatedly interrogating all said detector elements as a group while said mechanism rotates said circularly variable filter, thereby acquiring a plurality of acquired images of the scene, each said acquired image including a plurality of image portions, with each said image portion being acquired in a respective spectral band of said circularly variable filter, and (ii) assembling said image portions to form a plurality of processed images of the scene with each processed image depicting the scene in a single respective spectral band of said circularly variable filter.
