    Abstract: A Cascaded Mirror Array optical scanning system applies an array of reflectors, with each reflector (called array reflector for convenience) movable between discretized angular positions and independently switched by digitized electrical signals, to process a light beam by cascaded reflections to generate desired deflection angle of the beam. The precision of the discretized angular positions of each array reflector is maintained by a support structure, which supports the reflector while allowing it to rotate or tilt, and a set of positioning limiting structure, which limits the allowable angular position of the array reflector between a finite number of angular positions corresponding to the discretized angular positions.
