| Abstract: | Electronical Speckle Pattern Interferometry(ESPI) is an advance technology with all electronic image record , reconstruction and computer-aided image process. On the basis of concise introduction to ESPI and its application in measurement of fluid temperature field, it is emphasised how to find the best way to catch high-quality electronic fringe pattern by adjusting key parameters in the optical system. Some comparative test results are shown in this paper. |
