太赫兹技术应用进展
Progresses towards the application of terahertz technologies

近年来太赫兹技术的高速发展为太赫兹技术应用提供了基础。太赫兹以其高频率高穿透性以及低光子能量等优势,在多个领域受到了重点关注,并在多个具体的应用方向上实现了初步的探索。着重讨论用于高速率高带宽通信的太赫兹无线通信技术、用于生物化学物质检测研究以及用于医学领域的太赫兹光谱成像技术、用于无损探测系统的光谱成像以及谱分析技术、用于安全检查领域的太赫兹人体成像技术等太赫兹技术应用领域的进展,并对应用中存在的挑战进行了简要总结。

Science and technologies based on terahertz radiation have developed rapidly over the recent decades, which inspires the application attempts and research of terahertz technologies in several fields. Compared with the microwave or infrared waves, terahertz waves are of higher frequencies and lower photon energy. A variety of dielectrics are transparent with the terahertz radiation.Status and progresses in the field of terahertz communication, biological and medical application, non-destructive testing, and defense and security imaging are discussed in this work, as well as the challenges for real-life applications.
