Abstract
Apparatus for scanning the field of view of an optical objective. A primary mirror is mounted for rotation about a spin axis. A secondary mirror supports an electrical motor magnet and is mounted for rotation about the spin axis. A non-rotating stator is mounted behind the secondary mirror and supports the electric motor coils. The primary and secondary mirrors are canted slightly out of perpendicularity with the spin axis. The primary and secondary mirrors and the electric motor stator are fully gimbaled for tracking a target. The scanning patterns of the primary and secondary mirrors combine to scan a rosette pattern across a sensor.
