Temperature distribution as the flame propagated and approached the wall of the combustion chamber was measured by real-time holographic interferometry, which mainly consisted of an argon-ion laser and a high-speed video camera. The experiment was done with a constant volume chamber and propane-air mixture with several kinds of equivalence ratios. From the experimental results, it can be found that the temperature distribution outside the zone from the surface of the combustion chamber to 0.5mm distance could be measured by counting the number of the interference fringes, but couldn't within this zone because of lacking in the resolution of the used optical system. As a result of analysis, it was found that the minimum distance from the preheating place at 1200-1400K-temperature to the wall changed as the equivalence.
