Abstract:
A resonance locking system for a pico-projector, the system comprising a resonance frequency sensor operative for sensing change in resonance frequency of a miniature mechanical device (10) including a moving mirror assembly having a driving frequency, by comparing a current resonance frequency to a reference; and a feedback loop changing at least one aspect of use of the miniature moving mirror assembly responsive to a current value of the resonance frequency measured by the sensor.
