摘　　要：多通道近红外光谱技术用以对近红外光谱进行快速测试,但探测器的性能限制了测试的光谱范围.本篇论述了采用两波段双光谱仪器技术,即将700～1700nm波段分为700～1100nm与1050～1700nm两个波段的方法,实现宽波段的近红外多通道光谱测试的仪器设计.同时也对食醋、酱油、牛奶等进行了吸收光谱测试.The technology of multi-channel near-infrared(NIR) spectrum features in scanning spectrum in short time,but the spectral range is limited by NIR sensors available.This article describes the design of the multi-channel NIR spectrometer with wavelength of 700~1700nm by combining two spectrometers,one in 700~1050nm and another in 1100~1700nm.The spectrometer was used to measured the absorption spectrums of vinegar,soy sauce and milk and radiation of incandescent lamp and compact fluorescent lamp,the results was presented.
