本文研究了四种不同的过滤器组合对压敏涂料(PSP)样品的压力灵敏度、信号电平和温度灵敏度的影响。研究了空气物理实验室开发的两种不同的PSP配方，一种使用盐酸(PSP1-HCl)，另一种使用丙酮(PSP2-Ace)。这两种物质都被加入到一种溶胶-凝胶溶液中。结果表明，对于发射波长和激发波长选择不同的带宽、中心波长和滤光片透过率的效果会对PSP的行为、发光信号电平、压力和温度灵敏度产生显著影响，并且还可以消除影响最终结果的不需要的波长。
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.
