Terahertz (THz) electromagnetic waves have frequencies of order 10^12 Hz and wavelengths in the range of 100 micrometers. Terahertz spectroscopy for material imaging/sensing and characterization has received a great deal of attention over the past decade. It has been shown that many materials including organic materials, explosives, pharmaceutical compounds and biological agents have distinct signatures in the terahertz frequencies. It thus has potential applications in areas such as the pharmaceutical industry, food industry, organic light emitting diode, security, aerospace, oil industry, medical imaging, medicine, as well as high-data-rate communications.

太赫兹（THz）电磁波的频率为10^12赫兹，波长在100微米范围内。太赫兹光谱用于材料成像/传感和表征在过去的十年中受到了极大的关注。研究表明，包括有机材料、炸药、药物化合物和生物制剂在内的许多材料在太赫兹频率上具有明显的特征。因此，它在制药工业，食品工业，有机发光二极管，安全，航空航天，石油工业，医学成像，医学以及高数据速率通信等领域具有潜在的应用。
