  • Controlling opening angle of a resonating mirror
    Patent number: 10345577
    Abstract: A device described herein includes a movable MEMS mirror, with a driver configured to drive the movable MEMS mirror with a periodic signal such that the MEMS mirror oscillates at its resonance frequency. A feedback measuring circuit is configured to measure a signal flowing through the movable MEMS mirror. A processor is configured to sample the signal at first and second instants, generate an error signal as a function of a difference between the signal at the first instant in time and the signal at the second instant in time, and determine the opening angle of the movable MEMS mirror as a function of the error signal.
    Type: Grant
