| This article described the design and application of MCU in thesystem of measurement of whiteness.This system of whiteness is designed according to the basicknowledge about the colourity study, the luminosity study and theradiativity study. Halogen lamp to imitate the light source D65 tosight the sample, using d/o lighten to observe the geometricalcondition, using integral ball to stand upright normal ofsample, and receive the weak electric voltage signal from thesilion battery RCR. the instrument adopt the automotive controltechnology of MCU, it can complete the measurement of the physicaldata of the whiteness, measure lightness Y1, namely Ry, measuretransparentness and opaque degree, measure scattering(absorbing)coefficient.By voltage amplier, V/F invert, automotive processing to thedata, and then print the result, the result indicated:the systemworks stably and accurately.
