Dual plate Fourier transform interferometry combined with tomographic techniques was investigated to measure three-dimensional temperature profiles in a premixed flame. The dual plate method can overcome several problems and limitations of conventional Fourier transform interferometry. A six-directional two reference beams holographic interferometer is described, with which the conventional contour fringe and the modulated fringe can be obtained simultaneously. The results obtained are as follows. (1) It is not necessary to know the exact value of carrier frequency to extract the phase distribution from a modified interference fringe. (2) The inherent errors caused by the leakage of Fourier spectra and initial phase value are eliminated by its subtraction process. (3) Instantaneous spatial temperature profiles of a laminar premixed flame are presented.
