Title:
THERMALLY ACTUATED CANTILEVERED BEAM OPTICAL SCANNER
Document Type and Number:
Japanese Patent JP2023083315
Kind Code:
A
Abstract:
To provide a favorable thermally actuated cantilevered beam optical scanner.SOLUTION: 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 of 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.SELECTED DRAWING: Figure 2
