Control system for oscillating optical element in scanners |
摘要 |
A miniature light beam scanner includes a moving optical element formed on a substrate with electrodes for driving the optical element and sensing its motion as indicated by a varying capacitance between the optical element and the substrate. Control and driver circuitry responsive to the variation in capacitance drives the optical element to move at a resonant frequency and predetermined amplitude.
