• High-speed tomography for simultaneous measurement of a series of two-dimensional distributions of both temperature and density of species in the medium in a turbulent burnt gas is developed. The optical system consists of four sets of projections which simultaneously measure all the projection data by four photodiode arrays with each installed in respective projections for the acquisition of 35 sampling datums. The validity of the method is checked by simulations and by reconstructing the distributions of temperature and density of a pulsed flame jet. The temporal resolution is 1 ms and it yields a spatial resolution of 6.8 mm for a flame jet with a velocity of 3.5 m/s.
