Abstract :
An experimental characterization of the frequency response of a Pressure Sensitive Paint (PSP) has been performed. The PSP response to a sinusoidal pressure field was investigated. A Fourier analysis was then used to extended the results to a general periodic pressure field. Amplitude response and phase shift as a function of frequency are presented. The techniques developed in this paper are suitable for comparing the unsteady characteristics of various PSP formulations. Additionally, the frequency response characterization may be used in dynamic compensation techniques to correct for PSP time lag
