Abstract

We present fundamental limits on the strain resolution of phase sensitive distributed acoustic sensing based on considerations of thermal noise. These limits suggest that, despite ongoing advances, distributed sensors are unlikely to approach the sensing performance of traditional geophones and hydrophones.
