Abstract

PURPOSE:To enable correct measurement of surface temperature of a matter by determining a quantity of energy radiated from the matter itself based on the emissivity of the surface to be measured obtained from the intensity of a laser beam which is emitted from a laser beam source and reflected on the surface like a mirror. CONSTITUTION:First from the intensity of a laser beam which is emitted from a laser beam source and reflected on the surface to be measured like a mirror, an emissivity of the surface is determined. Then, a cooled shielding plate is used to shield a laser beam so that a quantity of energy radiated from the surface only is measured. Thus, the temperature of the surface to be measured is obtained from both values. For example, a laser beam from a laser beam source 20 is reflected like a mirror on the surface 12 to be measured and measured with a radiation thermometer 16. It is possible to determine the emissivity of the surface from the results, quantity of energy of the source and diffused reflection factor of the surface. Then, the laser beam is shielded with a water-cooled shielding plate 18 to be measured. In this manner, the surface temperature of a matter can be measured simply at a high accuracy from the measured value and said emissivity.
