Distributed Acoustical Sensing (DAS)

Sist oppdatert: Feb 21, 2020

NORCE has trough several large projects developed a unit for Distributed Acoustic Sensing (DAS). This unit is used as a research platform in various projects providing users access to raw data. The technology is based upon the analysis of backscattered signals from laser pulses propagating in an optical fibre giving spatial resolved measurement along the entire fibre.

We are currently working on enhancing signal processing and machine learning algorithms to better recognize and quantity different features influencing the optical fibre. The technology is generic and can be used in a wide range of applications. NORCE has primarily focused on application within monitoring of geological storage of CO2, inflow in wells and traffic monitoring.
