储粮品质太赫兹光谱检测技术研究进展
摘要：粮食质量与安全问题备受国民的关注，了解粮食在储藏过程中品质的变化趋势，特别是在早期阶段对其劣变状况进行快速、准确检测是当前粮食行业的重要任务之一。太赫兹光谱探测与成像技术具有快速、无损、衰减性小、无电离辐射伤害等特性现已成为无损检测技术的研究热点，在人体安全检查、环境监测、病变诊断、农产品质量控制等诸多领域取得了阶段性进展，在储粮品质检测方面也具有良好的应用前景。本文主要对太赫兹时域光谱技术的探测原理和光学参数提取以及成像技术进行了综述，重点阐述了该技术在储粮品质鉴别与分类、储粮新陈度、储粮真菌污染、以及储粮害虫检测方面的应用研究，并对太赫兹光谱技术在粮食品质快速检测中的发展趋势和应用前景进行了展望。
ABSTRACT：The quality and safety of food grain have attracted national attention. It is one of the important tasks for grain industry to understand the changing trend of grain quality during storage, especially to detect its deterioration quickly and accurately in the early stage. Terahertz (THz) spectroscopy detection and imaging technology has become a research hotspot because of its fast, non-destructive, low attenuation and no ionizing radiation damage. It has made progress in many fields, such as human safety inspection, environmental monitoring, disease diagnosis, agricultural product quality detection and so on. It also has a good application prospect in quality detection of stored grain. The principle, parameters extraction and imaging technology of THz spectroscopy are reviewed in this paper. In addition, the applications of identification and classification, freshness, fungal contamination and insects of stored grain were emphatically expounded. Finally, the development and application prospects of THz spectroscopy in the rapid detection of grain quality were prospected.
