Title of seminar: High-Spatial-Resolution Dynamic Distributed Fiber-Optic Sensors: Instrumentation and Applications
Abstract :
For the past decade, Thales Research & Technology has been developing an architecture for high-spatial-resolution (＜10 cm) dynamic distributed fiber-optic sensors (＞kHz) based on a proprietary frequency-modulated laser source. I will present the general concepts of our interrogator, the associated instrumentation challenges—particularly the significance of laser source noise—as well as several applications for acoustic, mechanical, and hydrodynamic measurements.
