Recently pressure sensitive paint (PSP) has actively developed to measure continuous distribution of the surface pressure. However, the pressure range has been limited above l Torr (133.3 Pa) and there is no application to lower pressure range because the pressure sensitivity seems to be not so high in that range. In this study, we apply three types of PSP [two types are composed by organic dye and polymer (luminophore/binder) ; PtOEP/GP 197 and PtTFPP/poly(TMSP), and another one is Bath-Ru adsorbed on anodized aluminum] to the rarefied gas flow mainly lower than l Torr and examine those fundamental properties, such as pressure/temperature sensitivity and time response of luminescence and so on, leading to selection of the most suitable PSP among them for the low pressure range. Finally, the pressure distribution of the surface on which a low density supersonic free jet impinges is measured by the PSP.
