| Abstract: | The principle of particle sizing by method of dynamic light scattering is reviewed. By analyzing the relative error, the method of segmental auto correlation is presented. The problems of high speed and large amount data acquisition are solved by using the proposed method. The accuracy of correlation function is not affected seriously. The experimental set up and results are shown. The measured result is in agreement with the nominal values. |
