Abstract
Disclosed is a method of measuring the surface temperature of a metallic body. The method comprises: disposing a reflecting member such that the reflecting member constitutes a resonator in cooperation with a substantially flat surface of the metallic body; measuring the mean reflectivity of the resonator over a predetermined frequency band having a center frequency coinciding with the resonance frequency of the resonator, as well as the luminance temperature of the resonator; and computing the surface temperature of the metllic body from these measured values. Disclosed also is an apparatus for carrying out this measuring method. The method and apparatus are suited particularly to the measurement of the surface temperature of a steel sheet heated to a temperature ranging between 500.degree. and 800.degree. C.
