Principal component analysis of dual-luminophore pressure/temperature sensitive paints

Abstract

Multi-luminophore pressure/temperature sensitive paints are investigated using principal component analysis of the spectral emission from the coatings. Two formulations are investigated. The first consists of Ru (4,7-diphenylphenanthroline) dichloride (Ruphen) and Coumarin-7 luminophores. The second coating contains Pt(II) meso-tetrakis (pentafluorophenyl) porphine (PtTFPP) and diethyloxadicarbocyanine iodide (DOCI). The principal component analysis revealed that the Ruphen/Coumarin-7 coating requires three fundamental spectra or modes to adequately model the coating emission characteristics. The PtTFPP/DOCI coating was modeled adequately with only two modes. Analysis of the PtTFFP/DOCI coating also revealed that a temperature independent calibration of the pressure sensing function could be developed. The requirement for a wind-off reference image was also eliminated.
