Outline of Final Research Achievements

The pressure-sensitive paint (PSP) technique has received much attention, as this technique enable us to measure pressure distribution. The PSP technique is an optical measurement technique based on oxygen quenching of luminescence. The application of PSP to pressure measurement near an atmospheric pressure is very difficult, because PSP is an absolute pressure sensor and it is difficult to detect small changes in luminescent intensity of PSP induced by small pressure changes. In this study, the heterodyne method was applied to the PSP technique. This method records the luminescent beat signal that result from interference between the PSP emission and modulating illumination light. The proposed method enables the precise measurement of pressure fluctuations, because only the signal at the frequency of interest can be detected. The 1 kHz pressure fluctuation of 50 Pa was successfully measured by this technique.
