In this paper, the intensity based measurement method, which is the typical method used in pressure-/temperature-sensitive paints (PSP/TSP) technique, is reviewed. First, the measurement principle of the intensity based PSP/TSP method is introduced. Then, a typical measurement system and procedure are introduced. For example, the apparatus for the intensity based method is described. and the characteristics of each apparatus and the points to be noted in using them is also summarized. We discuss the error sources contributing to the uncertainty of the measurements such as the photodegradation of dye and the surface temperature distribution for the PSP measurements. Finally, some applications of the intensity based method to the pressure-temperature measurements are shown.
