Data for: Application of Terahertz Time Domain Spectroscopy for NDT of Oxide-Oxide Ceramic Matrix Composites

In this paper the measurement results show the feasibility of the pulsed terahertz technique for NDT of oxide-oxide CMC materials. Hidden defects, delamination or moist areas can be detected quantitatively. Furthermore, the boundary reflections of layered materials can be revealed more clearly by using deconvolution algorithms.本文的测量结果证实了脉冲太赫兹技术应用于氧化物-氧化物陶瓷基复合材料（oxide-oxide CMC）无损检测（Non-Destructive Testing，简称NDT）的可行性。该技术可对隐蔽缺陷、分层区域及受潮部位实现定量检测。此外，借助反卷积算法，层状材料的界面反射信号可被更为清晰地呈现。
