This study examined the computational cost and uncertainty for various lifetime based post-processing methods on thermographic phosphor thermometry. Four different post-processing methods including two kinds of two-point methods, a three-point method, and a decay slope method were selected to conduct the comparison with the conventional lifetime method. Computational cost, uniformity and uncertainty were studied. These five methods were then demonstrated in temperature measurements of the curve surface under an impinging jet. The results show that the three-point method and the decay slope method have the better temporal and accuracy performance on temperature measurement.
