利用近红外光防治储粮害虫罗家传美农业研究局的科学家，首次利用近红外光（ＮＩＲ）与粮食自动处理系统联合，以监测小麦的储藏害虫。该仪器是将分光计与数粒器联合，数粒器可逐粒将小麦送到检验室供ＮＩＲ扫描，分光计为光传感器，可根据麦粒吸收和反射的光来区分麦粒和害虫 Using Near-Infrared Light to Prevent Stored Grain Pests Luo Jia-chuan, a scientist at the Bureau of Agricultural Research of the United States, is the first to use near-infrared light (NIR) in conjunction with automated grain handling systems to monitor stored pests in wheat. The instrument combines a spectrometer with a logger. The logger sends grain to the inspection room for NIR scanning. The spectrometer is a light sensor that distinguishes between grain and pests based on light absorbed and reflected by the grain
