The one dimensional(1-D) USED CARS experimental system was constructed. The 1-D CARS spectra of N2 Q-branch were obtained from the air as well as premixed CH4/Air flame with the equivalence ratio phi being 1, the flux per minute of methane being 0.7 L, at the atmospheric pressure. The data were analyzed by CARS software, and temperature was calculated. The temperature distribution in small range at various height above the burner was given in four fragments. The temperature in the flame decreased with increasing height, not only in the scale of the width of laser sheet, but also in the whole flame, by the influence of the air around the burner. The uncertainty of the experimental result is less than 7%. This technology can be used to measure the temperature in stable combustion field.
