A sense of the absolute

Philip Orr

Research output: Contribution to journalArticle


The paper demonstrates a technique that adds absolute FBG reflected wavelength determination to any passive phase demodulation technique based FBG multiplexing system. Their technique and wider system could find applications in areas from smart grids to nuclear power via hydrophones.
