MF3.3 - INTRINSIC FABRY-PEROT INTERFEROMETER FOR VIBRATION MEASUREMENT BY ENHANCED RAYLEIGH BACKSCATTERING DOTS FABRICATED BY FEMTOSECOND LASER INSCRIPTION
Abstract
Abstract
A new vibration measurement scheme is developed with an intrinsic Fabry-Perot interferometer (IFPI) built by two enhanced Rayleigh backscattering dots fabricated by femtosecond laser inscription. The cavity length of IFPI is absolutely and real-timely demodulated by fast white light interferometer demodulation.
MF3.4 - OPTICAL SENSOR BEHAVIOR PREDICTION USING LSTM NEURAL NETWORK
Abstract
Abstract
Optical fiber-based-sensors proved capable of enduring various harsh environments. Long-short-term memory (LSTM) neural-networks are often used for datasets with long-dependences. Here, rare FBG measurements collected from a neutron reactor core were used to build a neural-network capable of predicting the future events inside the reactor.

Abstract
Abstract
A temperature-independent bending sensor is proposed and developed based on hollow core microstructured optical fiber (HC-MOF). The device consists of a section of HC-MOF sandwiched by two segments of single mode fibers with the central-alignment. The nonlinear bending response is simulated and demonstrated experimentally.
