摘　　要：各种复合材料广泛地使用于现代工业生产中。由于复合材料的复杂性,常规无损检测技术往往不再适用。对基于亚毫米波技术的复合材料检测技术作介绍。给出了有限元模型,并提出了基于简单信号处理算法的重构技术。Today modem industry make very extensive use of various composite materials. Because of complexity of such structures, abilities of commonly used NDT methods sometimes are not sufficient. More advanced techniques should be utilized. In this paper T-Ray （terahertz radiation） method is presented for the purposes of various composite materials evaluation. Finite Element Method modeling of terahertz evaluation is shown and reconstruction procedure based on basic signal processing algorithms was proposed.
