• The temperature and density distributions of the components of burnt gas are the controlling factors for increasing thermal efficiency and the life of gas turbines. Optical method of measurement of gas temperature with computed tomography (CT) requires accurate knowledge on the absorption coefficient of components of the gas to be measured. But this effect has been neglected in the past works. In this report, the local absorption coefficient of particular components such as H_2O of both unburnt and burnt gases or CO_2 of burnt gas is measured by CT which makes use of the signals of an infrared radiation pyrometer. The coefficient is used to compensate by iteration the effect of self-absorption upon the local temperature obtained by CT. The validity of the CT algorithm is checked by simulation of model gases and the measured data are compared with the one obtained by other means.
