Paper Abstract

Present communication reports investigations undertaken towards testing applicability of Talbot interferometry for measurement of impurity in water. Because of presence of impurities in water, the refractive index of the sample (water) changes. The variation of refractive index is mapped as change in the fringe order of the Talbot interferometric fringes. Experimental investigation with ethanol and salt water as impurities has been reported. High accuracy and precision has been achieved.
