N2 - The single-shot interferometric imaging of normal mode dynamics in MEMS resonators, oscillating in the radio frequency (rf) regime, is demonstrated by synchronous imaging with a pulsed nanosecond laser. Profiles of mechanical modes in suspended silicon and graphene thin-film structures, and their extracted equilibrium profiles, are measured through nondestructive all-optical Fabry-Perot reflectance fits to the temporal traces. As a proof of principle, the modal patterns of a microdrum silicon resonator is analyzed, and its extracted vibration modes and equilibrium profile show good agreement with other characterization and numerical estimations.
