Abstract

PURPOSE:To perform optical axis adjustment easily even during working of a furnace by mounting a laser oscillator to a radiation meter by aligning incident radiation and optical axis. CONSTITUTION:The photodetector 16 of a radiation meter 14 measures the temp. of a strip in a high-temp. state by detecting the radiation 26 which is the sum of the radiation 24 projected from a black body radiation source 12 to a strip 10 and specularly reflected from a measurement point 10a and the radiation released by the strip per se. On the other hand, the laser light 50 from a laser oscillator 48 specularly reflects at the measurement point 10a, is projected to the black radiation source 12, reflects on the bottom part thereof and returns again to the meter 14. A mirror 22 is scanned horizontally or vertically by a motor 56, and adjusting mechanisms 28, 38, 42, 44, 46 are so operated that the peak part indicating the photodetecting output of the laser beam appears roughly at the center. Thereby, the optical axis alignment of the radiation meter and the black radiation source is accomplished easily.
