Paper Abstract

A 3D thermal field has been analyzed using a rotating interferometer. By rotating, the interferometer the multi- direction interferograms of the tested field are captured by a CCD-computer system and stored into computer. After processing multi-direction interferograms by the image- processing and reconstruction software the multi-direction data are obtained. The multi-layer thermal field distributions are reconstructed using the same software. All process is finished within a few minutes and a complete 3D thermal field is obtained. The result is well fit to the conclusion gained by thermocouple.
