Major Field of Science: | Engineering and Technology | Field Category: | Electrical Engineering - Electronic Engineering - Information Engineering | Λέξεις-κλειδιά: | Fibre Bragg gratings;Gamma radiation;Polymer optical fibres | Ημερομηνία Έκδοσης: | 1-Ιου-2019 | Πηγή: | Sensors, 2019, vol. 19, no. 13, articl. no. 2853 | Volume: | 19 | Issue: | 13 | Περιοδικό: | Sensors | Περίληψη: | We present a polymer fibre Bragg grating sensor and its sensitivity to gamma radiation by observing the reflected spectral profile. The Bragg grating is femtosecond inscribed within a perfluorinated CYTOP fibre and the alteration of the Bragg wavelength corresponds to the total radiation dose received. Over a total dose of 41 kGy, the fibre demonstrates a sensitivity of −26.2 pm/kGy and a resolution of 40 Gy. Under active consideration for the instrumentation of nuclear waste repositories, this study gives a better understanding of the effects of gamma radiation upon Bragg gratings in CYTOP fibres. | URI: | https://hdl.handle.net/20.500.14279/18987 | ISSN: | 14248220 | DOI: | 10.3390/s19132853 | Rights: | © 2019 by the authors.
