Abstract
Real-time measurement of temperature field is an important but very difficult problem in metallurgy, welding and various hot working process. The authors proposed a colorimetric method for measuring temperature field with ICCD as sensor. Two filters with different wavelength are mounted on a high speed rotating disk in front of the ICCD, so that two images can be taken by ICCD quickly and successively for the colorimetric estimation. Temperature range which can be detected by the designed device is 1100 approximately 1600 K. The measuring time for one field is less than 120 ms. Due to the inherent law of the method, the distance between the object and device has no effect on the measured results, therefore it does not need calibration for measurement at different position, which is one of the great advantages of the proposed method.
