Paper Abstract

The light scattered from the `rough' surface of a porous body illuminated by a narrow laser beam is carrying the information on geometrical micro structure of this surface. It is possible that the water vapor and water droplets in pores will cause changes in scattered light too. The aim of this paper is to present the results of the experimental investigations of the intensity of a helium-neon laser light reflected by a porous and moist gypsum slurry surface. Experiments show that the scattered light intensity increases with the decrease of the moisture content in porous material.
