摘要：A method of measuring temperature comprises the steps of consecutivelylaunching (1, 2) input pulses of light at two different wavelengths into a temperaturesensing element in the form o' an elongate optical fibre (3); passing Raman scatteredlight from said element and deriving from said input pulses to intensity detectors (7, 8);obtaining from the detectors (7, 8) output signals indicative of the intensity of the Ramanscattered light; and processing said output signals to provide a temperature

measurement. A known position (10) along the optical fibre (3) is maintained at a knowntemperature to provide a reference for deriving temperature measurements at otherpositions along the optical fibre.
