A very high resolution distributed optical-fiber temperature sensor system has been demonstrated using a time-resolved photon counting technique. The spatial resolution of the system is 3.5 cm. A temperature sensitivity of 2 degrees Celsius has been achieved with 1 minute integration time when averaging the data points over 10 cm. The system offers a practical solution for life assessment and monitoring of hot spots along the steam pipes in power plants.

Challenging the notion of equal modal power distribution in multimode optical fibers
In this paper we report both theoretical and experimental evidence that equal MPD is extremely unlikely in few mode fiber, and next to impossible to achieve in highly multimode fiber. In oneExpand
