在这项研究中，提出了一种基于O2-LIPF（激光诱导预解离荧光）的二维温度测量方法，使用宽带ArF准分子激光。在该方法中，通过使用在包括峰的两个光谱区域中积分的荧光强度之间的比率的温度依赖性来测量温度。为了减少测量时间和提高测量精度，我们研制了一种立体观察器，它可以将两幅图像通过两个不同的滤波器放在一个画框上。将该技术应用于加热空气射流，并将x / D=6（x：距喷嘴的距离; D：喷嘴直径）处的径向温度分布与用热电偶获得的温度分布进行了比较。并成功地测量了射流的二维温度图像。
In this study, a method for two-dimensional temperature measurement based on O2-LIPF (laser-induced predissociative fluorescence) using a broad band ArF excimer laser is proposed. In this method, temperature is measured by the 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 technique 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.
