Abstract

See full text

Embodiments of optical scanners, optical projection systems, and methods of scanning optical waveguides and projecting images are described. The disclosed devices, systems and methods advantageously provide an improvement to the compactness, robustness, simplicity, and reliability of optical scanners and optical projection systems by implementing a thermally driven actuator for inducing oscillations of a cantilever within the optical scanners and optical projection systems. The stability and accuracy of optical scanners and optical projection systems are further enhanced using capacitive sensing, feedback, and phase correction techniques described herein.
