Abstract:
An electromechanical device comprising:a first frame having a first aperture therein;a second frame suspended in said first aperture, said second frame having a second aperture therein;a plate suspended in said second aperture having a reflective surface for reflecting a signal directed to said plate;a first pair of beams which support said second frame along a first axis relative to said first frame so that said second frame rotates about said first axis relative to said first frame;a second pair of beans which support said plate along a second axis relative to said second frame so that said plate rotates about said second axis relative to said second frame, and wherein said first axis and said second axis intersect, wherein at least one end of at least one of said beams of said first and second pair of beams comprises a rotational contact that miniminizes torsional forces in said beam;a first actuator which provides mechanical force for rotating said second frame relative to said first frame about said first axis;a second actuator which provides mechanical force for rotating said plate relative to said second frame about said second axis so that said plate can be independently rotated relative to said first axis and said second axis; anda laser which generates a beam of electromagnetic radiation and directs said beam toward the reflective surface of said plate so that a reflected be can be scanned by rotating said plate.
