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.
