摘要

比较了脉冲压缩技术在涡流和LED热成像中的应用。报告并讨论了在具有冲击损伤的专用样品上取得的结果。基于巴克码的相同脉冲压缩程序已应用于这两种技术，并证明在这两种情况下都能正常工作。从脉冲压缩后的时间响应中提取和成像了两个不同的特征。

An Experimental Comparison of LED and Eddy Current Pulse-Compression Thermography on an Impact Damage CFRP Benchmark Sample

A comparison of the application of Pulse-Compression to eddy-current and LED thermography is presented. Results achieved on a dedicated sample with an impact damage are reported and discussed. The same pulse compression procedure based on the use of Barker codes has been applied to both techniques and it proved to be work properly in both cases. Two different features have been extracted and imaged from the retrieved time-responses after pulse-compression.
