Seminar: Fiber-optic Distributed Acoustic Sensing: Energy, Engineering and Global Seismology Applications

by Dr. Martin Karrenbach, Senior Manager Innovation, OptaSense Ltd

Tuesday 09 April 2019, 11AM – 12 PM, ARRC Auditorium

ABSTRACT: Distributed Acoustic Sensing (DAS) has matured into a technology that has found applications in many different scientific and industrial fields. Using a laser source, a standard telecom-grade optical fibre can be turned into an array with thousands of virtual sensors. All electronics are located away from the sensors, enabling deployment in circumstances where high pressures, high temperatures or other constraints preclude traditional electronic sensing systems. The availability of thousands of sensors along the fibre yields large amounts of high resolution data which can be used in novel algorithms and analysis techniques. After a short introduction to the physical measurement principles, we will show a variety of recent energy, engineering and global seismology applications.
