Coherent Laser Remote Structural Analysis

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。

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.
