METHOD FOR ALIGNING CONSECUTIVE SCAN LINES ON BI-DIRECTIONAL SCANS OF A RESONANT MIRROR

摘要

A method for aligning consecutive scan lines (72) of a mirror based visual system produced by the bi-directional scan of a resonant mirror (80) is disclosed. The actual position for the mirror is determined or measured by any suitable method. The measured position of the mirror (80) is used to generate a first trigger signal to start a scan line (72a, 72c) in a first direction at a selected location and to generate a trigger to start a scan line in the reverse direction (72b, 72d) at a second location.
