Abstract

An interferometric fiber optic temperature sensing system employing a light emitting diode (LED) as the broadband optical source and a single mode fiber coil, which was fabricated in definite length as the sensor head, is described. The fiber transmitting line back and forth along the same path is used, so the changing caused by the environmental temperature fluctuation of the fiber path can automatically be compensated. The sensitivity of the sensing system can be easily improved by using the long length of the sensing fiber. The experimental result of the sensing gauge length vs. the sensitivity is given. A typical wavelength 1300-nm LED source is used in the experiments. The experimental curve of the resolution characteristic of the system related with the length of sensing fiber coil is also discussed. (C) 2000 Published by Elsevier Science B.V.
