Abstract

PURPOSE:To reduce errors in the measurement of material by surveying the material with a radiation thermometer is such a direction that the reflection factor can be minimized with respect to a polarized component within the plane vertical to the surface thereof, including the optical axis convering the material while a polarization plate is provided to absorb polarization components. CONSTITUTION:A radiation thermometer 17 covers a billet 3 running in a furnace 2 at an angle 18 of thetaB. The value of thetaB is so set that the reflection factor can be minimized with respect to polarization components within an incidence plane between the optical path involving the radiation thermometer and a perpendicular 19 to the surface of the billet. A polarization plate 20 able to transmit said polarization on components as much as possible is provided on a photo detector section of the radiation thermometer 17 to absorb a component polarized vertical to the incidence plane. This controls the mixture of stray light and enhances the eissibity of the billet 3 thereby reducing errors in the measured value.
