Popis:	A method for measuring local flame temperatures using a spectral-ratio pyrometer and a tomographic system based on this method are described. The theoretical substantiation of the proposed measurement method is given. A block diagram of the system containing four measuring mirrors and one multiplexing mirror is shown. The results of the computer simulation are presented, with which it is possible to estimate the error of the system depending on the number of mirrors used in it. The software developed for carrying out measurements with the maximum degree of automation under the test-bench conditions is described. The results of an experimental study using the tomographic system for measuring the field of local flame temperatures of a gas burner (in the range of 1500–2300 K) are presented. The results demonstrate the operability of the developed system.
