resented at the 11th CIRP Conference on Photonic Technologies (LANE 2020) © 2020 The Authors. Published by Bayerisches Laserzentrum GmbH We introduce an effective application of a novel laser-based optical microphone for in-situ monitoring of cracks during laser metal deposition (LMD) processes. The system relies on XARION’s technology, a membrane‐free optical microphone based on a Fabry–Pérot laser interferometer, that captures broadband airborne acoustic emission up to 1 MHz such as the sudden acoustic emission signals...
