随着时间反演声学和非线性弹性最近在机械损伤成像中的应用，基于时间反演的无损评估技术的发展已经开始。在这里，使用时间反转弹性非线性诊断来分析包含故意脱粘区域的扩散粘合金属盘。将非线性结果与线性超声成像（C 扫描）进行比较。扫描电子显微镜显示了线性和非线性方法所观察到的特征之间的差异。
With the recent application of time reversed acoustics and nonlinear elasticity to imaging mechanical damage, the development of time reversal based nondestructive evaluation techniques has begun. Here, diffusion bonded metal disks containing intentionally disbonded regions are analyzed using the time reversed elastic nonlinearity diagnostic. The nonlinear results are compared with linear ultrasonic imaging (C scan). Scanning electron microscopy is shown to illustrate the differences between the features seen by the linear and nonlinear methods.
