Contrôle de la pollution de l’eau par méthode acousto-optique

Abstract

Most societies of the world obtain drinking water, from surface, rivers and lakes; water is always sensitive to contamination released from houses, farms, factories and hospitals. The augmentation of contamination has a direct relation with the number of the population (demographics). For this two reasons, purification and of drinking water is necessary to protect the community before the use of water. The propagation of ultrasound in the elastic medium (liquid ...) result in a change in its refractive index, the with electromagnetic waves gives us the phenomenon of diffraction. In this paper, we have a new research and applications based on the phenomenon of diffraction to control water pollution.
