title: High-speed stroboscopic imaging with frequency-doubled supercontinuum.
abstract: We present a supercontinuum (SC) light source designed for stroboscopic white light interferometry. The compact, cost-effective SC source is built from off-the-shelf optical components and operates both in the visible and near-IR at arbitrary repetition rates in the 10 kHz-1 MHz frequency range. We estimate that our source allows performing dynamic white-light interferometric characterization of rapidly oscillating objects up to several tens of megahertz. Its current potential is demonstrated by capturing the movement of a microelectromechanical system oscillating at 2.16 MHz with sub-100 nm accuracy.
