| 摘 要： | 太赫兹空气相干探测技术是一种宽带太赫兹探测技术。由于探测带宽仅受到探测激光脉冲宽度的影响，该技术的响应范围能够达到几十太赫兹，因此在实验上研发成功之后便成为了太赫兹技术领域一项重要的探测技术。详细介绍了太赫兹空气相干探测技术的实验原理和实验光路，总结了该技术最近几年的研究进展及改进措施，并对其探测性能和使用特点进行了分析与讨论。该研究可对初步使用太赫兹空气相干探测技术起到很好的参考作用。

| Abstract: | The terahertz air coherent detection technology is a broadband terahertz detection technology. Since the detection bandwidth is only affected by the pulse width of the probe laser, the response range of this technology can reach tens of terahertz, so after successful experimental research, it has become an important detection technology in the field of terahertz technology. The experimental principle and experimental optical path of the terahertz air coherent detection technology are introduced in detail, the research progress and improvement measures of the technology in recent years are summarized, and its detection performance and use characteristics are analyzed and discussed. This research can provide a good reference for the preliminary use of terahertz air coherent detection technology. |
