1. Optical Fiber sensing of acoustic waves using overlapping FBGs
University essay from Mittuniversitetet/Institutionen för elektronikkonstruktionAbstract : The objective of this thesis was to investigate if an optical fiber sensing method with the use of two overlapping fiber Bragg gratings to measure Lamb wave $S_0$ modes in a steel plate, and how it would compare to traditional PZT transducers. A solution was proposed where the use of an optical fiber sensing system was built and took advantage of the strain dependence of a fiber Bragg grating mounted to a steel plate. READ MORE
