The newly designed lifetime imaging system (LIS), which consisted of a multi-gated CCD camera and LED illuminator, has been developed to simultaneously measure temperature and pressure. The new system could reduce the measurement error due to shot noise of a CCD and laser speckle. Optimization of PSP film thickness and renewal of data reduction method were also conducted for improving measurement accuracy. As a verification test, pressure and temperature images on a simple delta wing were visualized by the newly designed LIS. The quality of pressure image was considerably improved in comparison with one measured by the previous system and biluminophor paint. These results indicated that the new LIS has a useful tool to simultaneously measure pressure and temperature image on an aerodynamic model surface. Besides, measurement accuracy of the new system was evaluated in comparison with pressure tap data.
