Tech Talks: Photonics/Optics

Innovations in Distributed Acoustic Sensing


This Tech Talk looks at how to achieve improved distributed acoustic and vibration sensing using optical fiber with continuous, grating-enhanced backscattering. It examines how increasing the power budget of distributed optical fiber acoustic and vibration sensors can provide freedom to system designers, offering a practical, cost-effective tool for satisfying system requirements. This is especially important for the aerospace industry, which contends with the twin challenges of weight reduction and crack detection. Viewers will be able to submit questions and download the report on which this Tech Talk is based.
