通过对铝合金蒙皮粘接层反射回波振幅的超声扫描，观察到了由于粘接层厚度变化而产生的干涉条纹。为了证明在逐点超声扫描中可观察到全场干涉图案，在水浸槽中超声扫描牛顿环的光学设置。超声波扫描显示出明显的牛顿环，其半径与预测非常一致。
Interference fringes due to bondline thickness variation were observed in ultrasonic scans of the reflected echo amplitude from the bondline of adhesively joined aluminum skins. To demonstrate that full‐field interference patterns are observable in point‐by‐point ultrasonic scans, an optical setup for Newton’s rings was scanned ultrasonically in a water immersion tank. The ultrasonic scan showed distinct Newton’s rings whose radii were in excellent agreement with the prediction.
