Stereoscopic audio-band vibrometry with source triangulation and interferometric sensitivity

Zhang, Ya; Zhao, Yuwei; Bandutunga, Chathura; Gray, Malcolm B; Chow, Jong


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