JAXA's practical Pressure-Sensitive Paint (PSP) measurement system is introduced. The detail of the system and data proseccing method are described. Global PSP results were measured in transonic and supersonic wind tunnel tests. These results were quntitatively good agreement with pressure tap data. Comparison with CFD was also performed.
