摘要: The invention is a temperature sensor which uses the variation in the critical angle between two optically transparent media, at least one of which has an index of refraction variable as a function of temperature, to variably refract and reflect portions of a spectrum incident on the junction of the media at angles less than and greater than the critical angle to produce an optical signal variable as a function of temperature.
