Effects of filters on the performance and characteristics of pressure-sensitive paints
Effects of filters on the performance and characteristics of pressure-sensitive paints
The current study investigates the effect of four different filter combinations on the pressure sensitivity, signal level and temperature sensitivity of pressure-sensitive paint (PSP) samples in an a priori calibration. Two different PSP formulations developed at the Aero-Physics Laboratory are studied, one using hydrochloric acid (PSP1-HCl) and the other acetone(PSP2-Ace). Both are incorporated in a sol–gel solution. The results show that the effect of choosing different bandwidths, central wavelengths and transmissions of the filters for the emitted and excitation wavelengths can have a significant impact on the behaviour of PSP,luminescent signal level, pressure and temperature sensitivity, and also eliminate the undesired wavelengths which can affect the final results.

Abstract
The current study investigates the effect of four different filter combinations on the pressure sensitivity, signal level and temperature sensitivity of pressure-sensitive paint (PSP) samples in an a priori calibration. Two different PSP formulations developed at the Aero-Physics Laboratory are studied, one using hydrochloric acid (PSP1-HCl) and the other acetone(PSP2-Ace). Both are incorporated in a sol–gel solution. The results show that the effect of choosing different bandwidths, central wavelengths and transmissions of the filters for the emitted and excitation wavelengths can have a significant impact on the behaviour of PSP,luminescent signal level, pressure and temperature sensitivity, and also eliminate the undesired wavelengths which can affect the final results.
