摘要
激光技术现已成功应用于农作物组分检测、长势监测、病虫害监测、农药残留检测、田间杂草识别及辅助精细农业操作等方面,并日益凸显出检测准确、快速、低成本等优势,在农作物检测中应用较多的激光技术主要包括激光漫反射技术、激光诱导荧光光谱技术和激光拉曼光谱技术。笔者重点介绍了这3种技术用于农作物检测的原理、系统构成、应用进展和发展趋势。
With the advantages of high monoehromaticity, coherence, compressibility and collimation ,laser technique has been widely used in military, mapping,and medical areas. In recently years, the application of laser in agriculture has caught much attention. Laser has been successfully used in the crop component detection, growing status evaluation, disease and insect pest monitoring, pesticide residual detection,Iuderai discrimination, and also be used for the assistant of precision agriculture. In the field of agriculture, laser appears significant advantages of accuracy,rapidity, and low cost. Three important laser technologies were discussed, including laser scattering technology, laser-induced fluorescence spectroscopy,laser raman spectroscopy. The principle, system structure, application progress, and developing trend of these three laser technologies in crop detection were investigated.
