Low-loss, low-cost spontaneous Brillouin-based system for simultaneous distributed strain and temperature sensing

Summary form only given. The ability to perform long-range distributed sensing fibre strain and temperature measurements with a high spatial resolution has many applications including power utilities, oil industries and structural monitoring. We present results using a novel signal detection technique for resolving independent strain and temperature measurements by obtaining both the spontaneous Brillouin backscattered intensity and frequency shift at every point along the sensing fiber.
