  • Abstract
    A fibre-optic thermometer is described which uses a thick-film SiC sensing etalon. The etalon´s temperature-dependent phase shift is determined by analysing its spectral reflectance, using an LED and a tunable Michelson interferometer. Temperatures from 20 to 1000°C are measured with better than 0.5 deg C resolution.
