太赫兹(THz)科学将深刻影响生物技术。它在成像、医疗诊断、健康监测、环境控制以及化学和生物识别等方面具有巨大的应用潜力。太赫兹研究将成为21世纪最有希望的研究领域之一，因为它将在成像以及其他跨学科领域取得革命性的进展。然而，太赫兹波(T-ray)成像仍处于初级阶段。本文讨论了T射线成像的独特性和局限性，确定了阻碍T射线成像的主要挑战，并提出了该领域的解决方案和机会。它还专注于利用飞秒光学技术产生、传播和探测T-射线。
Terahertz (THz) science will profoundly impact biotechnology. It has tremendous potential for applications in imaging, medical diagnosis, health monitoring, environmental control and chemical and biological identification. THz research will become one of the most promising research areas in the 21st century for transformational advances in imaging, as well as in other interdisciplinary fields. However, terahertz wave (T-ray) imaging is still in its infancy. This paper discusses the uniqueness and limitations of T-ray imaging, identifies the major challenges impeding T-ray imaging and proposes solutions and opportunities in this field. It also concentrates on the generation, propagation and detection of T-rays by the use of femtosecond optics.
