In order to investigate the influence of the scattering light generated from liquid surface on speckle patterns  the liquid surface contour was dynamically detected by WYKO during nano-particle movement. The result demonstrates that the fluctuation of fluid surface is slight. Meanwhile  in order to further analyze this effect  a piece of ground glass was employed. The process of ground glass to be polished to optical glass was studied and tested continuously using WYKO and laser speckle technology. And then  the speckle patterns generated from kerosene fluid surface were studied. By contrast  the results show that  the fluid surface is transparent to the measurement wavelength. The influence of the surface of fluid can be neglected. Furthermore  the conclusion illustrates that laser speckle technique is an effective and reliable method to study the movement of nano-granular in fluid.
