The research team from the Center for Information Photonics and Communications at the School of Information Science and Technology published their latest research results on large-scale, high-throughput distributed optical fiber sensing in Light: Science & Applications (Impact Factor: 20.6), a Nature sub-journal in the field of optics. The research paper entitled “High-spatiotemporal-resolution Distributed Brillouin Sensing with Transient Acoustic Wave”, was released online, marking the team’s second Nature sub-journal publication this year, with the University as the primary affiliation, and Tsinghua University and Shanghai Jiao Tong University as collaborating institutions. Professor Yan Lianshan serves as the corresponding author.
