报道了利用太赫兹技术对七种包装材料的实验研究,通过分析其吸收系数曲线和折射率曲线,讨论了太赫兹辐射对这七种包装材料的透射特性。实验结果表明太赫兹辐射对大多数包装材料有很高的透射特性,可以作为在安全检查领域中的一项有效手段。
The experimental studies on seven kinds of wrappers by using terahertz technology are reported, and the transmission characteristic of terahertz radiation to wrappers by analyzing absorption coefficient and refractive index of the materials are discussed. The results show that terahertz radiation has strong penetrability to most of wrappers, and the technology can become an effective means in the field of security inspection.
