Abstract
A temperature measuring apparatus utilizing the temperature dependence of the characteristics of fluorescence and afterglow emitted from a fluorescent substance by exciting the substance. The fluorescence and afterglow emitted by the excited fluorescent substance are detected and converted to electric signals. The fluorescence signal and afterglow signal are integrated for a predetermined period of time to obtain an integral amount of light. The temperature is determined by comparing the integral amount of light with the temperature characteristics of an integral amount of light preset for the fluorescent substance.
