Bridges require routine inspection to detect flaws before they lead to damage and dangerous conditions. The objective of this project is the application of coherent laser vibration to detection of flaws by remote inspection. The method will apply a laser technique to pinpoint flaws in individual structural elements of this bridge. Phase I demonstrated the technique on the total structure and was successful in detecting mechanical changes in the total system.

桥梁需要进行常规检查，以便在缺陷导致损坏和危险情况之前发现它们。本项目的目标是将相干激光振动应用于缺陷的远程检测。该方法将应用激光技术来精确定位这座桥的各个结构元素中的缺陷。第一阶段在总体结构上演示了这项技术，并成功地检测了整个系统中的机械变化。
