Abstract:
1. A micromirror array device comprising at least two of a plurality of zones of separately controllable tiltable reflective elements, each of the tiltable reflective elements of a zone being tiltable about an axis of predetermined tilt orientation associated with the zone between a first reflecting position reflecting an incident beam to a predetermined first “on” direction shared by all reflective elements of said at least two of plurality of zones, and a second reflecting position reflecting the incident beam to a predetermined second “off”direction, each of said at least two of a plurality of zones having a predetermined off direction for all the reflecting elements in that zone, that is different from the off direction of at least one other zone of said at least two of a plurality of zones, wherein each of said at least two of a plurality of zones having a predetermined tilt orientation for all the reflective elements in that zone, that is different from the tilt orientation of at least one other zone of said at least two of a plurality of zones.
