Abstract
Sensing rigs used for Brillouin scattering based distributed strain and temperature measurements so far have comprised separate sections of sensing fiber subjected to either temperature or strain influences. We demonstrate a scheme that allows for temperature corrected distributed strain measurements under environments involving simultaneous application of strain and temperature, with enhanced spatial resolution of 5 cm. Strain and temperature resolution of 63 με and 2 °C are reported. To the best of our knowledge, this is the highest spatial resolution temperature compensated distributed strain sensor result so far.
