Abstract
Disclosed herein is a method of controlling beam scanning timing and beam energy and a light beam scanning apparatus using the method. The light beam scanning apparatus includes a beam generation and processing means, a calculation and control means, a diffraction and scanning means and a scanning and processing means. The beam generation and processing means generates a beam and converts the beam into collimated light. The calculation and control means calculates scanning periods and beam energy, controls the operation periods and diffraction amounts of pixels of a light modulator. The diffraction and scanning means diffracts and modulates the beam and scans a plurality of diffracted beams.
