Optical Low Coherence Detection Technology of Material Micro Cracks
摘 要
以材料的微观裂纹为检测对象,基于扫频光学的低相干技术原理,设计构建了马赫-泽德干涉结构的低相干系统,采用平衡探测器接收干涉光信号,并通过LabVIEW软件平台实现数据的采集与存储,得到了叶片微观裂纹的二维信息,再据此对该裂纹进行了图像重构。系统的检测分辨率可达到15.6 μm,该方法具有非侵入、检测分辨率高等优点。
Abstract
An optical low-coherence system including Mach-Zehnder interferometer is designed and applied to measure material micro cracks. Light signals are received by a balance detector, and are collected and then stored on LabVIEW platform. Images of micro cracks are reconstructed based on two-dimensional information of engine blade cracks. Its resolution is up to 15.6 μm. This method has advantages of noninvasion and high resolution.
