Distributed acoustic sensing (DAS) in optical fibers detect dynamic strains or sound waves by measuring the phase or amplitude changes of the scattered light. This contrasts with other distributed (and more conventional) methods, such as distributed

We propose a novel method to improve the spatial resolution of Brillouin optical time-domain reflectometry (BOTDR), referred to as synthetic BOTDR (S-BOTDR), and experimentally verify the resolution improvements. Due to the uncertainty relation betwe

The paper deals with the design and principles of the hybrid Brillouin-Rayleigh sensing system. The system is capable of separating strain and temperature values in single SM fiber and offers spatial resolution as high as 2 cm. Furthermore, the paper

A number of distributed fiber optic strain sensing systems are proposed that are based on the frequency shift of the Brillouin scattered light power spectrum in proportion to the strain produced in the fiber. Although the spectral shape under a unifo
