Abstract
The PSP measurement technique is a non-contact pressure measurement method based on the oxygen quenching of the luminescence. Since the luminescence intensity of PSP depends on temperature as well, PSP result has to be corrected by the temperature distribution on the measurement surface. Also, position misalignment between wind-on and wind-off images reduces the measurement accuracy in the PSP measurement. In order to correct the temperature effect, combined PSP and TSP sensors such as mixture sensor, multi-layers sensor and multi-arrays sensor have been developed. Among these sensors, the multi-arrays sensor is favorable sensor from a view of the interaction between PSP and TSP luminophores. In this study, we attempt to correct the positon misalignment between wind-on and wind-off images by using the dot arrays of the dual-array sensor as markers. The result shows that it is possible to roughly correct positions between wind-on and wind-off images, but the correction accuracy is not enough yet.
