在本文中，我们介绍了一种使用平面波和基于飞行时间（TOF）的传输方法的一次性测量，并使用波传播模拟验证了该方法。即使在钢坯的表面附近，也能够与缺陷位置无关地检测钢坯的缺陷。虽然与传统的 TOF 传输法相比，TOF 偏差更小，且 TOF 偏差处的传感器位置 $X$ 范围更宽，但使用 TOF 平面波的一次性测量可以加快传输法钢坯检测的速度。
In this paper, we introduced a one-shot measurement using plane-wave with time-of-flight (TOF) based transmission method and validated the method using wave propagation simulations. The defect in billet can be detected regardless of the defect position even in the vicinity of the surfaces of a billet. Although TOF deviation is smaller and range of transducer position $X$ where TOF deviates are wider than that of conventional transmission method with TOF, one- shot measurement using plane-wave with TOF can accelerate the speed of the inspection of steel billet using transmission method.
