Abstract

A distributed fiber optic temperature sensing system was developed which consisted of a high-resolution optical time domain reflectometer (OTOR) and a special optical fiber sensor. Several 1 kilometer lengths of prototype sensing fibers were formed by coating a modified, ultraviolet light curable polymer cladding material onto a core glass during fiber production. By monitoring changes in Rayleigh backscattered light from the fiber; local temperature changes were measured along the fiber length. A demonstration system was assembled with a 20 meter sensing fiber and extensive data were collected. These measurements indicated that hot spots as small as 10 cm could be detected over a temperature range of 0 to 150°C with a measurement accuracy of ±°C
