Laser Interferometry for Study of the Diffusion Process in Glycerol−Water System

Mutual diffusion process in glycerol−water system was studied by laser interferometry technique. Descriptions of optical schemes, experimental technique using multi-beam laser microinterferometer and method of digital interferogram processing are presented. Kinetics of spatial distribution of the refractive index of a medium during mass transfer process is determined and diffusion coefficients are found.
