摘　　要：为了提高测色仪的稳定性,减小测量误差,对测色仪的照明系统,探测系统和数据处理系统进行了分析,对光源的选择,积分球的材料,噪声的抑制采取了一些改进措施,并且以AT89C51RD2微控制器为核心,实现了对色样的颜色测量、色度数据存储和显示、数据分析及色差报告等功能。结果表明,提高了测色仪的测量精度及测量稳定性,减小测量误差,测量的重复性完全达到了国家计量院规定的s(△E)<0.2要求。In order to improve the stability and reduce the measurement tolerance of the color measurement instrument. Factors including the lighting system, the detecting system and the instrument structure are analysed. Photosource, material of integrating sphere and noise control are improved. Based on the kernel of the miro-controller system AT89C51RD2, all the functions such as signal sampling,data storage, and result display on LCD or output via micro-printer are realized. The result indicates that some improvements are achieved to increase the accuracy and stability. The survey duplication completely meets the requirement of s（ΔE） 〈 0.2 stipulated by National Bureau of Measurement.
