SPIE 10323, 25th International Conference on Optical Fiber Sensors, 1032337 (23 April 2017); https://doi.org/10.1117/12.22648890277-786X10.1117/12.2264889https://academica-e.unavarra.es/handle/2454/34828In this work, a preliminary study of the behavior of two different interferometric fiber optic sensors and two different wavelength selective fiber optic sensors is performed. A photonic cristal fiber Fabry-Pérot interferometer, a Sagnac interferometer, a commercial fiber Bragg grating (FBG) and a π-phase shifted fiber Bragg grating interrogated in a random distributed feedback fiber laser are analyzed. A comparison of their sensitivities and resolutions is carried out to analyze their performance as sensors for cryogenic temperatures, taking into account their advantages and drawbacks.4 p.application/pdfeng© 2017 SPIE.
