A Distributed Optical Fibre Acoustic Sensor With 8cm Spatial Resolution Based on Enhanced Backscattered Fibre
Hosted By: Fiber Optics Technology and Applications Technical Group
08 September 2022 12:00 - 13:00
Eastern Time (US & Canada) (UTC -05:00)In this webinar hosted by the Fiber Optics Technology & Applications Technical Group, the operating principle of the distributed acoustic sensor (DAS) will be introduced by Dr. Ali Masoudi from the University of Southampton. The optical setup used to achieve a high-resolution DAS with 8 cm gauge length based on ultra low-loss enhanced backscattering (ULEB) fiber will be presented and its operation will be discussed. Finally, the performance of the sensing system in terms of the strain sensitivity, frequency range, and dynamic range will be presented and the potential application of such sensing system will be discussed.

About the Presenter: Ali Masoudi, University of Southampton
Dr Ali Masoudi is a senior research fellow in the Optoelectronic Research Centre (ORC) at University of Southampton and leads the distributed optical fibre sensing group at the ORC. He received his PhD degree in 2014 for his work on distributed acoustic sensors. After receiving his PhD, Dr Masoudi designed and developed portable DAS units which he subsequently used in several industrial collaborations with entities such as Network Rail, BT, and Carbon trust. The DAS unit has also been used in several interdisciplinary collaborations with other research institutes such as National Physical Laboratory (NPL), the Institute of Sound and Vibration Research (ISVR), and National Oceanography Centre (NOC). He has authored 3 patents and published more than 50 papers in international scientific journals and conferences and has presented his research as an invited and keynote speaker on 5 different occasions.
