ABSTRACT: The refractive index of a liquid
medium is an important optical parameter since it exhibits the optical
properties of the liquid. Its values are often required to interpret various
types of spectroscopic data. The intensity distribution and contrast of image
speckle patterns obtained for Zamzam, bottled drinking and distilled waters are
investigated on a computer as a function of six discrete wavelengths across the
visible spectrum. The present novel computer simulation speckle photography
using Fourier transform study and the new theoretical background have been
confirmed with previous experimental results. Uncertainty of refractive index
measurements was studied on a wide range of discrete wavelengths using the
computer simulation and the new theoretical formulae.
