Paper Abstract

Two-color radiometry by a high-speed camera is effective to obtain the temperature distribution map of high temperature phenomenon, which changes its figure rapidly. We have developed the two-color method by a color high-speed camera and put it into practical use. However, in the case of phenomenon that has chemical luminescence besides the thermal emission, it is difficult to get accurate data from the method that measures visible wavelength images. In case that chemiluminescence is in visible wavelengths but not in near-infrared region, we can obtain high-speed NIR images and high-speed temperature distribution map by two frame-synchronized high-speed cameras which are equipped with NIR band-pass filters. We would report on the result of an experiment using an optical bench and software which we have developed.
