Noncontact and nondestructive measurements for determining flame temperature distribution are under investigation. This paper proposes a new method we have called infrared emission computed tomography to measure the temperature distribution in arbitrary transaxial layers of the flame by calculating the infrared radiation intensity emitted from a flame as the projection data. We developed an experimental system using an infrared sensor as the detector and applied our method to a laminar flame. W e obtained good images of the temperature distribution in a flame. In addition, temperature profiles obtained by this method were in good agreement with the results of the thermocouple probe measurement.
