  • Optical sensor with micro-electro-mechanical system (MEMS) micro-mirror array (MMA) steering of the optical transmit beam
    Patent number: 11835709
    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.

The MMA may be partitioned into segments to independently form and scan a plurality of optical beams, which may be used to scan the first or different portions of the scene. The different segments may be provided with reflective coatings at different wavelengths to provide for multi-spectral imaging. The different segments may be used to combine multiple optical sources to increase power or provide multi-spectral illumination.
