    Abstract

    We present the characterization of a novel design for a varifocal MEMS mirror with piezoelectric actuation and defocus movement up to 100 kHz. The device was simulated using a finite-element method, fabricated using a multi-user silicon-oninsulator process, and its mechanical response to piezoelectric actuation evaluated through laser vibrometry and a dynamic white-light interferometer.
