【摘要】 本文首次提出电子散斑照相技术的新概念,对散斑图的记录与再现全部由计算机来完成。这一技术既不需要全息干板,显影,定影等照相过程,也不需要光学再现过程,实现了散斑照相的全电子化。因此,该技术不仅可以实时地测量瞬态场,而且不需要暗室及其照相处理过程。这样为散斑照相技术走出先学实验室,实现仪器化创造了条件。有广泛的工程应用前景。本文给出了电子散斑照相的基本原理与实验结果,分析了实验参数对电子散斑照相的影响。更多还原

【Abstract】 In this paper a new idea of electronic speckle photography is first proposed. The record and reconstruction for a speeklegram are both completed by microcomputer. By using this technique, neither holographic piate and development process nor optical reconstruction is needed. Therefore, the dark room is no necessary. Thus, it makes the speckle photograph not only go out from an optical laboratory; but also become an instrument. As a result, the electronic speckle photography has a wide future of application in engineering. In this paper the basic principle and experimental results for electronic speckle photography are given. The effects of experimental parameters on electronic speckle photography are analysed.更多还原
