Abstract

PURPOSE:To make the measurement of the radiation of a general object possible without the influence of its emissivity by disposing a reference heat plate which releases radiation energy to an object to be measured between said object and a radiation detector, and changing the distance between the object and the reference heat plate. CONSTITUTION:A reference heat plate 2 of temp. Tc and emissivity epsilonc which releases radiation energy to an object 1 to be measured of temp. T and emissivity epsilon is installed by leaving a prescribed distance from the object 1. Further, a radiation detector 3 is provided to detect the radiation energy released by the object 1 per se through the aperture 2a of the plate 2 and the radiation energy of the plate 2 reflected from the object 1. The plate 2 is so arranged as to permit changing of the distance l from the object 1. If the ratios that the radiation energy from the plate 2 is reflected by the object 1 and is made incident to the detector 3 are determined beforehand, the temp. T is obtained at all times by movement of the reference heat plate.
