Fibre optic temperature sensing: A new tool for temperature measurements in boreholes

摘要

A fiber optic temperature sensing technique can be used under field conditions. There is a good reproducibility of the data, long-term and short-term temperature changes can be detected easily, and there is good fitting between standard thermal measurements in boreholes and fiber optic measurements. It is of special advantage that the fiber optic sensing cable can be installed permanently even under conditions where standard thermal borehole probes cannot be used.
