Work conducted recently on model analysis has shown that structural changes may be identified by analyzing changes in the vibration spectrum of a structure. Project will use coherent laser detection, a technique on which the laser vibrometer is based, to complement model analysis, thereby allowing the remote inspection of large structures for flaws. A major advantage of the laser technique is the ability to pinpoint structural elements by aiming the laser at each individually. This application of coherent detection will stimulate development of state-of-the-art laser- based systems with new, significant commercial applications which will benefit the US economy.

最近进行的模型分析工作表明， 可以通过分析振动中的变化来识别变化 结构的光谱。 项目将使用相干激光 检测，激光测振仪所基于的技术， 补充模型分析，从而允许远程检查 大型结构的缺陷。 激光的一个主要优点是 技术是通过瞄准来精确定位结构元素的能力 每个人的激光。 这种连贯性的应用 探测将刺激最先进的激光技术的发展， 新的，重要的商业应用， 将有利于美国经济。
