    Abstract
    We demonstrate the feasibility of enhancing the scanning rate for MEMS and diffraction based beam steering employing Digital Micromirror Device (DMD) by one to two orders of magnitude, which is configured as a programmable blazed grating. The tilt movement of micromirrors synchronizes with multiple pulses from multiple laser sources that sequen- tially redirect the pulses to multiple diffraction orders within μs. The approach opens up a pathway to achieve a LIDAR system with a scanning rate over 1M samples/s while leveraging a state of the art DMD and a moderate number of laser sources.
