| Abstract: | The holographic interferogram of the temperature field for an axisymmetrical high power semiconductor triode has been obtained by using laser holographic interferometric measurement. The projection value has been extracted by using MATLAB toolbox. The temperature field has been reconstructed by using Abel transform method and wavelets transform technique. The measurement result indicates that the spatial resolution is 0.051 cm, with the measuring error of <4.8%. |
