Single-end hybrid Rayleigh Brillouin and Raman distributed fibre-optic sensing system
Backscattered lightwaves from an optical fibre are used to realise distributed fibre optic sensing (DFOS) systems for measuring various parameters.Rayleigh, Brillouin, and Raman trea turner signature backscattering provide different sensitivities to different measurands and have garnered the attention of researchers.A system combining the three pri
