Abstract:
1. An electromagnetic scanning micro-mirror comprising: a magnetic field generator for supplying a magnetic field; a mirror plate having a reflective plane and a frame structure attached to a rear surface of the reflective plane, wherein the frame structure is an array comprising at least two unit frames, each of which has a width gradually decreasing away from a rotating axis of the mirror plate; a substrate to surround the mirror plate; a pair of torsion bars to connect the mirror plate to the substrate; and a magnetic substance provided at the rear surface of the reflective plane of the mirror plate and adapted to generate a drive force by interacting with the magnetic field supplied from the magnetic field generator, wherein the mirror plate performs a rotation operation about the torsion bars, which define the rotating axis of the mirror plate, by use of the drive force generated from the magnetic substance.
