| 中文摘要: |
| 太赫兹波具有许多独特的性质,有着广泛的应用 前景。然而,由于水汽对太赫兹波的强烈吸收,使 其在空气中的传输距离十分有限,应用受到了极大限制。TEA现象巧妙的将太赫兹波和光声 信号结合起来, 为太赫兹波的远程探测提供一种有效途径。本文初步探讨了TEA 现象的物理过程及其内在的 物理机制,推 导出了TEA过程的近似理论模型,得到了太赫兹辐射与光声信号幅度增强之间的定量关系。 |
| 英文摘要: |
| Terahertz (THz) waves have attractive prospect in application,because of its many unique properties. However,due to the intense absorption from vapor,the transmitting distance of THz waves in air is very limited, and its application is greatly restricted.Terahertz enhanced acoustics (TEA) phe nomenon provides an effective way for detecting THz waves remotely,through combining tactfully THz waves with photoacoustic signals. The paper studies preliminary the physical process and inner mechanism in TEA,an d acquires the quantitative relationship between THz emission and increase of photoacoustic-signal′s ampli tude by deducing theoretical model about TEA approximatively. |
