Fiberoptic Strain Measurements for Levy Monitoring : An FBG based system for thousands of sensing points

Fugro is a worldwide operating Geotechnical, Survey and asset monitoring company headquartered in The Netherlands. Over 50 years we have pioneered the geotechnical industry with groundbreaking technical inventions, starting from the cone penetrometer which led to the start of Fugro (“Foundationand Ground Mechanics”). In the current presentation we will introduce a Fugro developed fiberoptic measurement system, based on the use of discrete Fiber Bragg Gratings and some aspects of its performance, as well as a case study of the application of this system with over 700 sensors using a single fiberoptic interrogator system.
