Abstract: For looseness detection of bolted joins in large structures with a wide distribution span, a high-resolution bolt loosening angle detection sensor based on fiber Bragg grating (FBG) with an ...
Abstract: In this article, a fiber specklegram sensor (FSS) is formed from reflective mode rotation in few-mode fiber (FMF) with tilted fiber Bragg gratings (TFBGs). The FMF-TFBG with different tilt ...
