In this study, the frequency characteristics of fast-responding Pressure-Sensitive Paints(PSP) were evaluated by using a device based on an acoustic tube. The gain and phase characteristics of two different types of fast-responding PSP, Polymer-Ceramic PSP and Anodized-Aluminum PSP, were measured over the frequency range from 0.15 to 10 kHz and their dependence on binder, luminophore and temperature were investigated. From the measured frequency characteristics, the transfer functions were evaluated and the factors governing the time response of each PSP were estimated. The results of this study have suggested that luminophore molecules are distributed near the surface of PC-PSP and on the other hand are adsorbed inside the pores of AA-PSP.
