Abstract

In this paper, we use Laplace Transform Method (LTM) to reconstruct the temperature field generated by cylinder radiator, which can be treated as axisymmetric field. In the experiments, we found that LTM leads to fetal mistake when the relative shift of the fringe is large. We analyze the LTM and the reason is found, which shows that LTM constrained strictly in the reconstruction of axisymmetric field. We compared the different results under different conditions with the results measured by thermocouple axisymmetric field. We compared the different result under different conditions with the result measured by thermocouple.
