Recently, measurement method using pressure sensitive paint (PSP) and temperature sensitive paint (TSP) is attractive in measurement of pressure and temperature field on surfaces. However, PSP has temperature dependence as well as pressure sensitivity. Temperature dependence will be the factor which brings an error in pressure measurement using PSP, so temperature correction is needed to obtain the highly precise pressure distribution. So, in this research we apply use the combined method using both PSP and TSP by stacking PSP and TSP layer up. Using the combined method, the temperature distribution obtained by TSP can be used for the temperature compensation of PSP. We call this combined method as "Dual-layer PSP/TSP". In this research, we clarified that the sensitivity of the dual-layer PSP/TSP in low-speed flow fields against pressure and temperature is comparable to that of mono-layer PSP or TSP, showing the feasibility of the dual-layer PSP/TSP for the measurement in low-speed flow fields.
