摘要:
A two-dimensional light scanning apparatus includes: a deflector to drive at a resonance frequency in a main scanning direction and a sub-scanning direction different from the main scanning direction; a position sensor to detect a scanning position of the deflector; a resonance frequency predicting part to predict the resonance frequency of the deflector; and a deflector drive control part to: for drawing a Lissajous figure in which scanning trajectories of the deflector do not overlap with each other for one frame, store a plurality of pairs of respective frequency ratios of driving signals in the sub-scanning direction to driving signals in the main scanning direction, and respective phases of the driving signals in the sub-scanning direction with respect to the driving signals in the main scanning direction; select one pair of a frequency ratio and a phase; and control the deflector with a driving signal.
