Spectral signal quality of fast pressure sensitive paint measurements in turbulent shock-wave/boundary layer interactions

This study presents a critical investigation of the signal quality obtained using candidate fast pressure sensitive paint measurements in realistic, spectrally complex flows. The evaluations focus on characterizing the importance of the paint layer frequency response in conjunction with the fundamen...
