Many methods for gas-temperature measurement have been developed as temperature is one of the most important factors in a study of combustion. The major interest at present is concentrated on taking its two- or three-dimensional distribution. The methods developed for local-temperature measurement are Laser-Rayleigh pyrometer or CARS method. Another is computed tomography (CT). The former requires a great number of repesitions of experiments to map even a two-dimensional distribution of only one plane. On the other hand, the latter is not so troublesome. In this report an algorithm of an infra-red 2-band emission CT pyrometer is developed, and some practical examples of measurement are presented. It is made clear that this method is very useful to measure not only two-dimensional distrubution of temperature, but that of density of an optically active component in the burnt gas.
