SPIE 9157, 23rd International Conference on Optical Fibre Sensors, 915769 (June 2, 2014);0277-786X (Print)1996-756X (Electronic)10.1117/12.2059358https://academica-e.unavarra.es/handle/2454/22693We demonstrate a novel concept for Brillouin optical time domain analysis sensors that is based on synthesizing a virtual Brillouin frequency shift profile along the sensing fiber. The technique is based on modulating the wavelength of the optical source with a periodic waveform that is synchronized to the pump pulse. Application of this new tool to the compensation of non local effects and Brillouin induced noise in distributed sensors is experimentally demonstrated.application/pdfengCopyright 2014 Society of Photo Optical Instrumentation Engineers.
