摘要

为进一步实现红外热波无损检测中缺陷深度测量，提出基于脉冲位相分析的数据处理方法。对脉冲红外热波无损检测的时间信号进行傅立叶变换（FFT），提取位相频率信息，根据热波频率与传导深度的关系完成缺陷深度的检测。以热传导较快的铝材料为例，对自行设计深度不同的平底洞缺陷给出此方法的实验结果，通过Matlab中FFT分析得到的不同深度平底洞缺陷在不同频率下的位相曲线及VC++中得到的位相序列热图，实验结果表明了脉冲位相对缺陷深度检测的可行性，缺陷实际深度关系与实验计算深度存在d≈1.98μ 的关系，同时位相图有效抑制了噪声的干扰，为材料和结构内部缺陷检测提供了一种有效处理方法。

Abstract

In order to realize the defects’ depth measurement in the infrared thermal wave nondestructive evaluation

pulse phase thermography was introduced. Pulse phase method analyzes pulse data by Fourier transform to temporal signals

and measure the depth according to the relation of thermal wave’s frequency to conduction depth. In this paper

the experimental result of Al flat bottom holes sample is obtained by phase curves in Matlab and thermographs in VC++ under different frequencies. The initial result shows the theoretical depth and factual depth has d≈1.98μ

and pulse phase infrared thermography is an assistant way for subsurface defects detection of material and structure.
