Abstract
Disclosed herein is a control circuit for a movable mirror. The control circuit includes driving circuitry configured to drive the movable mirror with a drive signal to effectuate oscillating of the movable mirror, opening angle determination circuitry configured to determine an opening angle of the movable mirror, and amplitude control circuitry. The amplitude control circuitry is configured to a) first cause the driving circuitry to generate the drive signal as having an upper threshold drive amplitude, and b) then later cause the driving circuitry to generate the drive signal as having a nominal drive amplitude, as a function of the opening angle of the movable mirror being equal to a desired opening angle.
