A Chinese research team from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences (CAS) has developed a new method to enhance the practical performance of ...

Distributed acoustic sensors (DAS) can monitor mechanical vibrations along thousands independent locations using an optical fibre. The measured acoustic waveform highly varies along the sensing fibre ...

(a) Schematic illustration of the HW-TSC. The optical fiber was helically wound around a continuous mandrel to function as an acoustic sensor. (b) Photograph of the HW-TSC and the anechoic tank. One ...

Real-time wide-area environment sensing is crucial for accessing open-world information streams from nature and human society. As a transformative technique distinct from electrical sensors, ...

A new publication from Opto-Electronic Advances reviews advances in distributed fiber optic vibration/acoustic sensing technology. Distributed fiber optic vibration/acoustic sensing technology ...

Pipeline contents are typically valuable, volatile, and harmful to the environment if allowed to escape. With them being susceptible to aging, accidental damage, or tampering, the chances of an escape ...
