Abstract :
To measure the surface texture study on the aggregate, this paper based on the principle of laser light scattering method, using the PSD texture analysis, and adopt the existing laser equipment cross-section for the texture sensor, which issued by the laser through a laser beam collimating lens alignment group, setting to form a uniform surface scattering spot. The acquisition process with a laser signal demarcation and the horizontal displacement demarcation of the DC pulse. Also Matlab-based package of fractal analysis procedure Fractalyse can be used in different ways (Box, a small island law, the relevant law, etc.) to measure the fractal dimension of the image, and the process of analysis comes into two parts: the counting method and forecast model. By using the above ways to analyze and calculate the texture data, the fractal dimension have a certain degree of comparability.
