High Resolution of Ultrasonic Testing

本文介绍了一种从广泛使用的超声无损检测获得的绝对数据中估计实部和虚部的方法。进行了仿真和实验测试。首先，提出了探头流出超声强度分布的实部和虚部的确定方法。其次，提出了将无损检测结果应用于缺陷的实部和虚部的确定方法。因此，可以像模拟一样准确地估计缺陷的形状。

This paper describes a method to estimate real parts and imaginary parts from absolute data obtained from non-destructive ultrasonic testing widely used. Simulation and experimental test were carried out. First, the method to determine real parts and imaginary parts of a intensity distribution of ultrasonic flowing out of a probe is proposed. Next, the method to determine real and imaginary parts of a result obtained from non-destructive testing applied to a defect is proposed. Aa a result, the shape of a defect could be estimated as accurate as simulation.
