Abstract
An optical scanning system includes one or more Micro-Electro-Mechanical System (MEMS) Micro-Mirror Arrays (MMAs) used to scan a field-of-view (FOV) over a field-of-regard (FOR). The MEMS MMA is configured such that optical radiation from each point in the FOV does not land on or originate from out-of-phase mirror segments and a diffraction limited resolution of the optical system is limited by the size of the entrance pupil and not by the size of individual mirrors.
