摘　　要：基于多波段LED光源的新型藻类分类测量仪体积小、功耗小,并能够实现水体中藻类在线、快速、原位分类监测。针对该仪器的信号与噪声的特点,完成了仪器的检测电路设计。测试表明,设计的新型藻类分类测量仪对铜绿微囊藻、小球藻和汉氏棱形藻的检出限分别为0.4925μg/l、1.9351μg/l、0.8686μg/l.且藻浓度与荧光强度的线性相关系数均超过0.99,满足淡水藻类监测需要。Novel alga classified instrument based on multi-wavelength LED array is small size, low dissipation, and can achieve on-line, rapid, in situ and classified measure of alga in water. According to characteristics of signal and noise, detection circuit is designed. The experiment indicates that detection limits of microcystis aeruginosa, chlorella vulgaris and nitzschia hantzschiana reach 0.4925 μg/l, 1.9351μg/1 and 0.8686 μg/1 respectively, and its linear relation exceed 0.99. The parameters meet requirements of alga measurement in the normal water.
