Abstract

PURPOSE:To enable to detect accurate road surface temperature without injuring the advantage of the infrared-ray thermometer, by obtaining the temperature signal within a given range through two infrared-ray detectors and performing display if the difference of the signals is outside the set reference value. CONSTITUTION:The infrared-ray radiation thermometer 20 is mounted on the support stand 22 of the support 21, and it is provided with the two lenses 24-1, 24-2 independently receiving infrared-rays radiated from the two areas S1, S2 on the road 2a and the infrared-ray detectors 23-1, 23-2 afterwards. In front of each lens, the disc type chopper 26 is placed, and the windows 26-1, 26-2 having the size seeing through the areas S1, S2 are provided, and the infrared rays 6-1, 6-2 from each area are intermittently radiated on the detectors 23-1, 23-2 with a given period. The electric signal of pulse train shape corresponding to the surface temperature of each area and synchronized with each other is output from the detector. Thus, the road surface temperature can accurately be detected.
