【摘要】 本文提出一种莫尔云纹图象的频域处理方法。经光学干涉所产生的莫尔云纹图通过频域处理得到全场位移，进而求得全场的应变分布。该方法具有自动化程度高、信息量大、精度高、应用方便的优点。实例应用验证了该方法的优点和实用性。更多还原

【Abstract】 A process method of moiré image in frequency domain has been proposed in this paper Using process method in frequency domain to deal moiré pattern the full field stresses are obtained,then strain distribution gained by strain analysis method This method has merit such as high level of automation,dense data,high precision,and convenience in use The merit has been proved in practice更多还原
