Abstract

We demonstrate audio-band vibrometric measurements with interferometric precision using Digitally Enhanced Heterodyne Interferometry. We use the integrated time-of-flight readout from two multiplexed, spatially separate receivers to triangulate the source position down to 20 cm precision.
