We propose a new method for the 2-D temperature measurement technique using the LIPF (laser-induced predissociative fluorescence) of O_2 molecules excited by a broadband ArF excimer laser. In this method, temperature is measured by the use of temperature dependence of the ratios between fluorescence intensities integrated over two spectral regions. The method is applied to the temperature measurement of the flow field of a heated air free jet using a high-sensitive CCD camera and two band pass filters which pass through the different spectral regions. The radial temperature profiles perpendicular to the centerline of the free jet, which is measured using the proposed method, agree with those measured by a thermocouple within ±70 K, and a quantitative 2-D temperature image is obtained successfully.
