.A quasi-distributed dynamic and static strain sensor system[J].Optoelectronics Letters,2008,4(4):243-247 A quasi-distributed dynamic and static strain sensor system College of Precision Instrument ＆ Optoelectronics Engineering, Key Laboratory for Optoelectronic Information and Technical Science of Ministry of Education, Tianjin Universiey, Tianjin 300072, China Abstract:       A quasi-distributed dynamic and static strain sensor system consisting of 16 FBG sensors is designed by using an amplified-sponteneous emission (ASE) optical source, an optical tunable ftlter and a tunable las.er. Aresolution of about 5 με has been achieved for dynamic strain measurement. The resolution for static strain measurement is about 1 με. Hits: 3330 Download times: 230 View Full Text    Download reader
