The principles of operation, the design, and performance of a fiber-optic temperature-distribution sensor are discussed. The sensor uses optical time-domain reflectometry (OTDR) to detect temperature-induced changes of backscatter power at many separate locations in the fiber. In liquid-core fibers, a sensitivity of 2.3 x 10^-2 dB/°C (0.54 percent / °C) was observed. A measurement accuracy of 1°C with a spatial resolution of 1m is attainable over a fiber length of 100 m.
