In this study, a method for two dimensional temperature measurement based on O_2-LIPF (laser-induced predissociative fluorescence) using a broad band ArF excimer laser is proposed. In this method, temperature is measured by use of temperature dependence of ratios between fluorescence intensities integrated in two spectral region including peaks. To reduce the measurement time and improve the measurement accuracy, we develop a stereo-viewer which can put two images passed through two different filters on a picture frame. This method is applied to heated air jet, and radial temperature profile at x/D=6 (x : distance from nozzle ; D : nozzle diameter) is compared with that obtained with a thermocouple. Two-dimensional temperature image of the jet is also measured successfully.
