Abstract

Characterization of micromirror in terms of optical performance during actuation has always been chal-lenging. Two years ago, we introduced a method that makes use of digital holography and variable mirror positioning to sample the shape of the mirror at an arbitrary position in its movement. Here we present further development of the technique, including a methodology to perform fast frequency sweeps. We demonstrate the capabilities by comparing the deformation to analytical derivation from amplitude and frequency.
