Abstract

This study details the development and validation of an airborne THz spectrometer designed for real-time, remote detection of atmospheric pollutants. The platform couples a stabilized unmanned aerial system (UAS) with a high-resolution terahertz continuous-wave (THz-CW) laser source and detector, enabling flexible, in situ spectroscopic analysis of dispersed atmospheric vapours. This proof-of-concept investigation confirms the feasibility of UAS-THz-CW systems for spatially resolved environmental pollutant monitoring. The demonstrated capability of this terahertz sensor for remote, multi-component detection of atmospheric contaminants holds significant potential for advancing air pollutant monitoring technologies, providing a pathway for more effective and portable detection. This advancement can contribute to the necessary alert actions for minimizing contaminants impacting public and environmental health, thereby safeguarding human and ecosystem health.

推进机载太赫兹光谱仪大气污染监测

本研究详细介绍了用于实时、远程探测大气污染物的机载太赫兹光谱仪的开发和验证。该平台将稳定的无人机系统（UAS）与高分辨率太赫兹连续波（THz-CW）激光源和探测器相结合，实现了对分散的大气蒸汽进行灵活的原位光谱分析。这项概念验证调查证实了UAS-THz-CW系统用于空间分辨环境污染物监测的可行性。这种太赫兹传感器用于远程、多组分大气污染物检测的能力，为推进空气污染物监测技术提供了巨大的潜力，为更有效和便携的检测提供了途径。这一进展有助于采取必要的警报行动，尽量减少影响公众和环境健康的污染物，从而保障人类和生态系统的健康。
