Distributed acoustic sensing with ocean applications
The Journal of the Acoustical Society of AmericaExtensive monitoring of acoustical activities is important for many fields, including biology, security, and ocean and Earth science. Distributed acoustic sensing (DAS) is an evolving technique for continuous, wide-coverage measurements of mechanical vibrations across oceans.

Distributed acoustic sensing in shallow water
The Journal of the Acoustical Society of America, 2006The significance of Leonid Brekhovskikh to the ocean acoustics is undisputed. He was pioneering not only in terms of fundamental understanding of the ocean acoustic waveguide, but also the development of efficient and numerically stable approaches to propagation of sound in a stratified ocean. As such he has been an inspiration to a whole generation of

Quantum weak measurement enhanced distributed acoustic sensing
Optics LettersAn enhanced distributed acoustic sensing (DAS) is proposed based on an extended Mach–Zehnder interferometer utilizing quantum weak measurement. The acoustic signals are encoded as the relative phase of the polarized light in several channels by fibers between optical fiber Bragg gratings (FBGs).

Distributed acoustic sensing for volcano monitoring
This thesis explores the potential of distributed acoustic sensing (DAS) for volcano monitoring. The last decade has seen a rapid rise in the use of fibre-optic technologies for seismic sensing, of which DAS has been one of the most well-established. DAS interrogates an optical fibre, resulting in a seismic network with a high spatiotemporal resolution.openaire +1 more source
