Abstract: A beam steering architecture for an optical sensor is based upon a pair of Micro-Electro-Mechanical System (MEMS) Micro-Mirror Arrays (MMAs) and a fold mirror. The MEMS MMAs scan both primary and secondary FOR providing considerable flexibility to scan a scene to provide not only active imaging (to supplement passive imaging) but also simultaneously allowing for other optical functions such as establishing a communications link, providing an optical transmit beam for another detection platform or determining a range to target. A special class of MEMS MMAs that provides a “piston” capability in which the individual mirrors may translate enables a suite of optical functions to “shape” the optical transmit beam.
