The visualizing technique using the infrared radiometer, which is useful in estimating a two-dimensional temperature distribution on a surface, has been attractive. Infrared radiometry is one of the most fundamental methods of various remote sensing techniques. In the measurement using the infrared radiometer, radiation energy is analyzed to determine surface radiation temperature. However, the radiosity of the surface, which is a summation of emissive and reflective energy should be considered in measuring surface radiation energy. In particular, the influence of reflective energy on radiation energy transfer becomes important when measurement is performed at the normal temperature. In this study, we clarified various fundamental characteristics of infrared radiometry by use of 3 kinds of the infrared radiometer to visualize temperature distribution on a surface.
