Outline of Final Research Achievements

This research aims to reduce measurement error caused by position difference between luminescence images in a pressure-sensitive paint (PSP) measurement. PSP and temperature-sensitive paint (TSP) dots in the dual luminescent arrays sensor were used as markers to register each image positon. Luminescence intensity ratio images of PSP and TSP images were well calculated by the position correction method, the projective transformation. On the other hand, the registration between the luminescence intensity ratio images of PSP and TSP images could not archive enough accuracy because of large distortion. This research pursues higher correction accuracy by another correction method or by increasing the number of dots used for the correction.
