Correcting lifetime measurements for temperature

摘要: Abstract Typical pressure sensitive paint (PSP) methods use intensity measurements to predict the pressure. Unfortunately, there are a number of difficulties that arise when using measurements, such as: uneven illumination conditions, photodegradation, inhomogeneous coatings, and thickness effects. On other hand, lifetime free these problems. In addition, may be able eliminate troublesome `wind-off' condition by internal reference τ vac (the vacuum sensor). However, both require correction due temperature dependence paint. We propose method correcting for temperature. A non-oxygen quenched, temperature-dependent phosphor is added standard UW The determined from phosphor. Then, PtTFPP temperature-selected calibration curve, can calculated more accurately.
