ABSTRACT:
A fluorescent material arranged under an environment of temperature objective for measurement is excited by irradiating red color light or infrared rays, then fluorescent light generated from the fluorescent material is received by an optical sensor thus the temperature of the fluorescent material is measured from an output of the optical sensor on the basis of the correlation between a fluorescent characteristic of the fluorescent material and temperature.
