Paper Abstract

Using an optical fiber whose transmission loss depends in a linear way on temperature, a thermometric system can be designed that will allow direct measurement of the temperature averaged along the length of the fiber. This paper describes such a system used to test the feasibility of using rare earth-doped fibers in practical distributed measurements of average temperature.
