  • Doubly Resonant Micromechanical Beam Scanners
    Publication number: 20230266581
    Abstract: The present disclosure is directed toward systems and methods for steering a light beam within a field of view with better uniformity and/or density than achievable using prior art beam scanners. Beam scanners in accordance with the present disclosure include an optical element that is operatively coupled with doubly resonant tethers that enable motion of the optical element in at least one dimension, thereby enabling the beam scanner to realize scan patterns that are more complex than simple Lissajous curves. In some embodiments, doubly resonant beam scanners can steer a light beam in a Rose pattern, a combined Rose and Lissajous pattern, or more complex patterns.
