近年来,太赫兹光谱技术在安全检查、生物医学、食品检测、资源探测等领域展现了巨大的应用潜力,其中对农产品中农药残留进行检测是当前的研究热点之一。为此,系统地阐述了太赫兹光谱技术在农药检测领域的最新研究进展,梳理了太赫兹光谱实验仪器和理论计算方法,从农药的鉴定与识别、农药指纹数据库的建立、农药的定量与定性分析、农药的理论计算四个方面出发,对近年来国内外学者在该领域取得的研究结果进行总结,同时分析了目前存在的问题和今后的研究方向,对太赫兹光谱技术在农药检测领域的应用前景做出展望。

In recent years, terahertz spectroscopy has shown great potential in the fields of safety inspection, biomedicine, food detection, and resource detection. Among them, the detection of pesticide residues in agricultural products is one of the current research hotspots. This paper systematically expounds the latest research progress of terahertz spectroscopy in the field of pesticide detection, and combs the terahertz spectroscopy experimental instrument and theoretical calculation method. From the identification of pesticides, the establishment of pesticide fingerprint database, the quantitative and qualitative analysis of pesticides and the theoretical calculation of pesticides, this paper summarizes the research results obtained by scholars at home and abroad in recent years, and analyzes the existing problems and future research directions, which also provides prospects for the application of terahertz spectroscopy in the field of pesticide detection.
