Data reduction requirements for dual-luminophor pressure/temperature sensitive paints (P/TSP) are explored through the use of principal component analysis. The dual-luminophor coating contains one luminophor which primarily responds to temperature and one which responds to both temperature and pressure. The analysis indicates that a two-factor reduced order model based on two fundamental spectra represents the majority of the luminescence response but cannot properly account for mutual interaction effects between the luminophors. The inclusion of a third factor appears to sufficiently model the mutual interaction effects. This work indicates that P/TSP data reduction procedures based on principal component analysis are promising for improving the accuracy of the measurements. The potential to remove the requirement of a wind-off reference image and to reject high frequency noise is also indicated.
