| Title: | Limitation of absorption-based fiber optic gas sensors by coherent reflections | Authors: | Jin, W Stewart, G Philip, W Culshaw, B Demokan, S |
Issue Date: | 1-Sep-1997 | Source: | Applied optics, 1 Sept. 1997, v. 36, no. 25, p. 6251-6255 | Abstract: | We report the noise limitation of fiber optic gas sensors with highly coherent laser sources. Interference between signal and reflected waves causes signal fluctuation in the output; this limits the performance of the sensing system. Sensor resolutions limited by coherent reflections are calculated and compared with experimental results. | Keywords: | Fiber optic sensors Gas sensors Coherent reflections Interferometric noise |
