介绍了新建立的多功能农产品品质光特性无损检测系统,可由微机控制进行光谱数据的采集和分析,能迅速而准确地得到检测对象的反射光谱和透射光谱。自行设计的软件能完成对光谱数据的平滑处理、计算反射率、透射率和颜色参数、求微分光谱以及回归分析等处理。 This paper introduces the new nondestructive testing system of quality optical characteristics of multifunctional agricultural products, which can be used to collect and analyze the spectral data by computer control, and can quickly and accurately get the reflection spectrum and the transmission spectrum of the tested object. Self-designed software to complete the smoothing of spectral data, calculate the reflectivity, transmittance and color parameters, differential spectroscopy and regression analysis and other treatment.
