A simple method for the determination of the refractive index of liquids is demonstrated by using digital holographic interferometry (DHI). A number of experiments are performed to measure the refractive indices of liquid samples. Experimental results reveal that the deviation in refractive index measured by this method and that measured by Abbe refractometer are within experimental limits.
