Abstract
A beam scanning apparatus includes an optical source, a beam deflector having a deflection disk which is comprised of a plurality of sectors patterned to diffract a beam emitted from the optical source and has a reflective layer for reflecting an incident beam formed on the bottom surface of the beam deflector, and a driving source for rotating the deflection disk. A beam corrector is provided for correcting the beam deflected by the beam deflector.
Claims6
A beam scanning apparatus comprising:
- an optical source for emitting a beam of light;
- a beam deflector having a deflection disk which includes a plurality of sectors patterned to diffract the beam emitted from the optical source and a reflective layer for reflecting an incident beam and which is formed on a bottom surface of the beam deflector, and a driving source for rotating the deflection disk;
- and
- a beam corrector which corrects the beam deflected by the beam deflector,
- wherein each sector of the deflection disk has an incident region for receiving the beam emitted from the optical source and an emission region for emitting the beam reflected by the reflective layer, and the patterns are formed in the incident and emission regions, and
- wherein the patterns formed in the incident region and emission region are different.
