Pressure sensitive paint (PSP) is very powerful method to measure pressure on solid surfaces. However, PSP has not only pressure dependence but also temperature dependence. In addition, error caused by temperature dependence have a great effect on PSP sensitivity in low gauge pressure condition. Therefore, it requires temperature compensation for precise pressure measurement in low gauge pressure condition. In this study we show the characteristics of dual-layer PSP/TSP with lifetime based method using high speed camera. Firstly, we checked mono-layer PSP and TSP characteristics with lifetime based method and optimum measuring point. Then we show the feasibility of the temperature compensation of PSP for dual-layer PSP/TSP for the measurement in low-speed flow fields with temperature distribution.
