Method for aligning consecutive scan lines on bi-directional scans of a resonant mirror

摘要

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