  • Adaptive control of a fiber scanner with piezoelectric sensing
    Patent number: 10349818
    Abstract: Improved systems, methods, and devices relating to optical fiber scanners are provided. In one aspect, a scanning apparatus includes an optical fiber and a piezoelectric actuator coupled to the optical fiber to deflect a distal end of the optical fiber in a scanning pattern. The apparatus can include drive circuitry coupled to the piezoelectric actuator, sense circuitry electrically coupled to the piezoelectric actuator and the drive circuitry to determine displacement of the piezoelectric actuator, and a processor coupled to the drive circuitry and the sense circuitry to drive the piezoelectric actuator in response to the displacement.
    Type: Grant
    Filed: December 7, 2017
    Date of Patent: July 16, 2019
    Assignee: University of Washington through its Center for Commercialization
    Inventors: Ivan L. Yeoh, Per G. Reinhall, Eric J. Seibel, Matthew J. Kundrat

  • Methods of driving a scanning beam device to achieve high frame rates
    Patent number: 7784697
    Abstract: The present invention provides methods and systems for scanning an illumination spot over a target area. The present invention removes stored energy from a scanning element to stop the scanning element from vibrating and to substantially return the scanning element to its starting position so as to enable high frame rates.
