Publisher: | Spie-Int Soc Optical Engineering | Source: | Conference on Physics and Simulation of Optoelectronic Devices XXVI -- JAN 29-FEB 01, 2018 -- San Francisco, CA | Series/Report no.: | Proceedings of SPIE | Abstract: | Extinction ratio is an inherent limiting factor that has a direct effect on the detection performance of phase-OTDR based distributed acoustics sensing systems. In this work we present a model based analysis of Rayleigh scattering to simulate the effects of extinction ratio on the received signal under varying signal acquisition scenarios and system parameters. These signal acquisition scenarios are constructed to represent typically observed cases such as multiple vibration sources cluttered around the target vibration source to be detected, continuous wave light sources with center frequency drift, varying fiber optic cable lengths and varying ADC bit resolutions. Results show that an insufficient ER can result in high optical noise floor and effectively hide the effects of elaborate system improvement efforts. | URI: | https://doi.org/10.1117/12.2289488 https://hdl.handle.net/20.500.11851/6103 |
