Abstract:
An optical scanning apparatus is configured to include a light source that emits a beam of light, and a scanning device that scans the beam of light in two axial directions that are mutually substantially perpendicular at a first frequency fH and a second frequency fL. The scanning device calculates the first frequency fH and the second frequency fL by using predetermined mathematical formulas, and scans the beam of light at the calculated first frequency fH and second frequency fL.
