在把全息照相干涉量度术及斑纹计量术用于应力分析及其它工业应用方面,世界各国都取得了进展.最大的进展是用廉价微型计算机与高增益、低噪声电子仪器使数据简化. 两次曝光斑纹图的全息干涉照片的信息量相当于几百个应变仪的读数.但如不进行分析并迅速使用,时常是“实时”应用(指获得信息的同时就进行处理),绝大多数信息是无用的.
Progress has been made in the world in the use of holographic interferometry and speckleometry in stress analysis and other industrial applications, with the most significant progress being in the use of inexpensive microcomputers and high-gain, low-noise electronics to make the data simpler. The amount of information exposed by a streak pattern holographic interferogram is equivalent to hundreds of strain gauges, but if not analyzed and quickly used, it is often used in “real time” applications (referring to the processing of information while it is processed) Most information is useless.
