ABSTRACT:
The invention provides for an improved mirror scanning system for use with a millimeter wave imaging system. The mirror scanning system includes a pair of voice coil actuators aligned generally perpendicular to a mirror. The voice coils are intermittently energized pursuant to a predetermined frequency related to a desired resolution. A base supports a back plate that is generally disposed parallel to the mirror and secures the pair of voice coil actuators. A rod flexure is secured to a center yoke, or coil bobbin, of each of the respective voice coils and to a back side of the mirror so that the pair of rod flexures simultaneously exert a force on the mirror causing deflection thereon as the pair of voice coils are energized. Stationary position sensors are mounted adjacent to each cylinder so the sensor can determine to location of the cylinder, and hence the angle of the mirror.
