Abstract
A scanner for implementation with ladar, and visual band passive IR systems. An optic fiber is positioned such that one end thereof is maintained at the focal point of a lens system. A permanent magnetic is attached to the optic fiber near that end, with the permanent magnet being positioned within a space subjected to varying magnetic fields induced by pairs of orthogonally positioned electromagnets. The end of the optic fiber scans the image of the lens, with the scanning pattern being controlled by the varying magnetic fields induced by the electromagnetic pairs. Another end of the optic fiber is connected through a coupler to an infrared/optic detector and a laser diode. The coupler allows for duplexing of light energy from the laser diode to the lens and for the receiving of light energy from the lens to the detector.
