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.
