The Pressure Sensitive Paint (PSP) is very useful and easy way to obtain the pressure distribution on surfaces. The pressure distribution obtained by the paint shows good agreement with that by other methods, like a pressure tap. Recently, the paint has been adopted to the high Knudsen number regime. The mechanism of the PSP is mainly discussed within the framwork of the luminescence intensity and the oxygen quenching, while it is unclear that luminescence intensity is really proportional to the pressure, especially in the high Knudsen number regime. Usually it is considered that the luminescent represents a pressure, but it is not clear yet that this "pressure" means "static" or "total" pressure. Here, in this study, we tried to relate the flux of oxygen molecules and a pressure to the luminescence intensity, and clarify the limit of application from the molecular kinetics point of view.
