Abstract: A solid catadioptric lens (10) includes substantially planar input surface (14), primary concave mirror 18, secondary convex mirror (22) and substantially spherical exit surface (24). The lens is composed of solid material (12) chosen according to the particular imaging application in which the lens is to be used. Radiation enters lens through input surface (14), travels through solid material (12) and is reflected off of primary mirror (18). Radiation subsequently passes internally through solid material (12) and is reflected off of secondary mirror (22). Subsequent to being reflected off of secondary mirror (22), radiation (30) passes through solid material (12) and out of lens (10) through spherical exit surface (24) and onto detector array (34) for imaging purposes.

Abstract: A self-stabilizing optical scanner system comprising a multi-faceted mirror formed on or attached to a gyro rotor, which is adapted for being gimbal mounted, such that as each facet is rotated through the optical path of an energy receiving lens system, a detector is optically scanned across a field of view along a first dimension. In accordance with one embodiment, each mirror facet is inclined at a different angle to the rotor spin axis such that as the rotor revolves a two-dimensional pattern is scanned; and in accordance with a second embodiment a driven mirror is disposed in the optical path of the received energy so as to provide scanning along the second dimension.
