Paper Abstract

In this work, an optical method to characterize a turbulent liquid will be presented; it comes to measuring the content of a suspension in a liquid by laser scattering.

A laser beam transmitted through a transparent rectangular glass container including the emulsion of plaster is imaged using CCD camera, and the resulting image is processed to calculate the scattering intensity. Thus, a relationship between the concentration of the particles in the liquid and the full width at half maximum (FWHM) of the intensity profile of the scattered laser will be determined.

Furthermore, a measure of the contrast of an interference pattern obtained by Mach-Zehnder interferometer is achieved; the object beam passes through the glass container comprising the turbulent liquid. A correlation between the FWHM determined above and the contrast of the interference pattern as a function of the concentration of the emulsion will be deduced.
