ABSTRACT:
A micromirror system having at least two micromirrors, each suspended on a substrate wafer via at least one torsion spring. The axes of rotation of the micromirrors are disposed essentially perpendicular to each other in order to permit deflection of an optical beam in two directions essentially perpendicular to each other. The micromirrors and the torsion springs are patterned out of the substrate wafer and lie essentially in one plane.
