Distributed fiber acoustic sensing (das) technology can continuously spatially detect disturbances along the sensing fiber over long distance in real time. it has many unique advantages, including, large coverage, high time and space resolution, convenient implementation, strong environment adaptability, etc. nowadays, das becomes a versatile technology in many fields, such as, intrusion.

D0 B1 D0 Bb D0 B0 D0 B3 D0 Be D0 B4 D0 B0о Among the wide variety of distributed fiber sensing technologies, phase sensitive optical time domain reflectometry (Φ otdr) based on rayleigh backscattering stands out as the basis for distributed acoustic sensing (das), providing a revolutionary way for highly sensitive measurement of acoustic waves, vibrations, and disturbances (such as. Rayleigh scattering based distributed acoustic sensing (das) systems use fiber optic cables to provide distributed strain sensing. in das, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device. such a system allows acoustic frequency strain signals to be. We show that monitoring of volcanic events can successfully be performed with das data, thanks to its high information content. the das strain rate data reveal frequent transients (~30–35 events. On chip optoelectronic devices are promising to build compact and efficient distributed acoustic sensing (das) systems. here, the authors demonstrate an ultra high extinction ratio electro optical.
