摘要

对一种压敏涂料(PSP)的频率响应进行了实验表征。研究了等离子体对正弦压力场的响应。然后用傅里叶分析将结果推广到一般的周期压力场。振幅响应和相移作为频率的函数。本文所开发的技术适用于比较各种PSP配方的非定常特性。此外，频率响应特性可用于动态补偿技术，以纠正PSP的时间滞后。

Pressure sensitive paint: application to a sinusoidal pressure fluctuation

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.
