【 摘 要 】

In the work were proposed to use the method of digital holographic interferometry on the example of suspensions of fine dispersed silica, developed by different ways, for studying fine dispersed suspensions of inorganic substances in combination with the process of their sedimentation. A comparison of experimental results obtained by this method and by method of dynamic light scattering is presented. The high sensitivity of the interferometric method, particularly during assessing of changes of suspensions with nanosized particles is shown.
