High-resolution low-coherence Brillouin optical correlation-domain reflectometry with suppressed systematic error

Published 20 Apr 2023 in physics.optics and physics.ins-det | (2304.10111v1)

Abstract: We show that the systematic error unique to Brillouin optical correlation-domain reflectometry (BOCDR) can be effectively suppressed by use of low-coherence light, and demonstrate distributed strain measurement with ~3 cm spatial resolution.
