本文报导了一种具有独特能力的双板全息照相干涉仪系统及其技术和应用两方面的若干进展。首先,利用条纹图的微控技术的发展能够产生连续的干涉测量数据。其次,还讨论了一种新设计的六个自由度之间无联系的双板支架。其应用包括:采用条纹微量操作方法进行流场的定量测量,再入飞行器吹风的流场和发动机进气道附面层的相互干扰的分析。以上所列举的进展有助于研制自动全息照相干涉测量系统。
This paper reports a unique ability of the double-plate holographic interferometer system and its technology and application of a number of advances. First, the development of micro-control techniques using fringe patterns can produce continuous interferometric data. Second, it discusses a newly designed double-sided stent that has no connection between the six degrees of freedom. Its applications include: the use of streak trace operation method for quantitative measurement of flow field, reentry into the air flow field and the engine intake port surface interference analysis. The advances listed above have contributed to the development of automated holographic interferometry systems.
