Light beam scanning apparatus.

摘要

The present invention provides a light beam scanning apparatus employing a resonance scanner mirror (1), in which scanning position error is substantially eliminated by utilizing only a part of the total range of angular movement of the mirror (1) to scan across the body (3) surface, and by appropriately selecting the total angle of oscillation of the mirror (1) in accordance with the amplitude of that part of the mirror (1) angular movement which is utilized for scanning.
