|Fibre-optic thermometer using semiconductor-etalon sensor|
|Electronics Letters (ISSN 0013-5194), vol. 22, Feb. 27, 1986, p. 238, 239.
A fiber-optic thermometer is described which uses a thick-film SiC sensing etalon. The etalon's temperature-dependent phase shift is determined by analyzing 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.
