A Macro-Bend Fiber Based Wavelength Demodulation System For Optical Fiber Sensing Applications, Ginu Rajan
A Macro-Bend Fiber Based Wavelength Demodulation System For Optical Fiber Sensing Applications, Ginu Rajan
Doctoral
This thesis considers the design and development of a wide range allfiber interrogation system with a rapid measurement capability for extracting reliable measurand information from fiber Bragg grating sensors. Existing passive and active interrogation systems have certain limitations and do not satisfy all requirements. In this thesis a wavelength demodulation system is proposed, based on a macro-bend fiber filter employed in a ratiometric detection scheme. A theoretical model and analysis of an edge filter based ratiometric wavelength measurement (RWM) system is presented. A fiber edge filter is realized by carefully selecting an appropriate bend radius and number of bend turns …
