Asia Communications and Photonics Conference (ACP) & International Conference on Information Photonics and Optical Communications (IPOC)

Workshop 5: Fiber optics distributed acoustic sensors (DAS) and applications

Distributed acoustic sensing (DAS) is a technology that records sound and vibration signals along an optical fiber. Its advantages of high sensitivity, long distance, high resolution, continuous, and real-time measurements promote the wide applications. The workshop will present the latest research progress on principles, methods, and applications of fiber optics DAS.
