Demonstration of a Multi-channel Dynamic Interrogation System Based on Matched Filters for Elastic Wave Sensing (JTu1A.5)

Presenter: Aananth K, Indian Institute of Technology Madras

We experimentally demonstrate a dual-channel dynamic interrogator for elastic waves sensing using matched fiber Bragg gratings, with noise floor closer to theoretical limit using hardware filtering and computationally inexpensive signal conditioning.
