Abstract
Among the various fiber-optic sensors, sensors based on interference technique have the highest sensitivity. However, the range of temperature measurement is limited by their periodic natures. The purpose of this research is to improve this situation, and still keep their high sensitivities. We use two interferometers with slightly different sensitivities simultaneously, and the relative phase differences between two fundamental modes in the fibers are measured to determine the temperature. The purpose of extending measurable temperature range is achieved by combining the output signals of those two interferometers.
