In order to solve the problems(slow rate and big volume) which the existing color measuring instruments are confronted with,a mathematical model for color measurement was established with the advanced optoelectronic spectrograph method for color measurement and an automatical spectrophotometer was designed.The system consists of illumination system,optoelectronic spectrograph,signal collecting and processing circuit,and color measuring software.The design of the illumination system and optoelectronic spectrograph are introduced in detail.Photoelectrical spectrograph device uses a flat-field concave grating as a beamsplitting device and the linear array CCD as detectors,thus,the volume of instrument was reduced.Seven standard color boards were measured with the spectrophotometer,and the result is that the measurement uncertainty of chromaticity coordinate is less than 0.01 and color measurement period is 1 s.These indicate that the instrument can meet the requirements of rate and accuracy in color measurement in industry.

为解决目前颜色测量仪器测速慢、体积大的问题,采用先进的颜色测量方法——光电摄谱法,建立了一个测色的数学模型,设计了一种全自动测色的小型光谱色彩分析仪。仪器由照明系统、光电摄谱仪、信号采集与处理电路、测色软件四部分组成。详细阐述了照明系统和光电摄谱仪的设计。光电摄谱仪采用平场凹面光栅分光,线阵CCD接收,缩小了仪器体积。利用此仪器测量7块标准色板,色品坐标测量不确定度小于0.01,测试周期为1秒。结果表明,此仪器不仅精度高,还满足了工业生产中对测色的速度和准确度要求。
