Abstract

This paper describes progress towards the development and demonstration of a distributed fiber optic acoustic emission sensor (FAESense™) system for the in-situ unattended detection and localization of structural damage caused by shock events, impacts, fractures, cracks, voids, corrosion, and delaminations in new and aging infrastructures found in the petroleum and chemical industries, solar and wind power plants, nuclear, coal, and gas utilities industries, in civil and geophysical engineering, biomedical engineering, aerospace and naval industries, and transportation security. The FAESense™ system is based on the use of a novel two-wave mixing interferometer produced on a photonic integrated circuit (PIC) microchip.
