Abstract

A novel fibre-optic temperature sensor using the red fluorescent emission from ruby crystal, wavelength separated to provide a temperature variant region and a self-generated reference region is described. The principle of this device relies on separating optically the R-line, the variant quantity, from the total emission, which is used to supply the reference. The ratio of the two quantities is then taken to give an accurate temperature measurement which is then calibrated against a standard thermometer. From the calibration curve, a linear profile is seen in the temperature range 293 to 433K and the accuracy of the probe was recorded to be +3K with the response time limited by the mechanical construction in this early work. The upper range level is limited by deviation in the quantum efficiency about 500K.
