Abstract: A simple and compact interferometric system, which makes use of a reflective-type diffraction grating, has been developed for measuring the refractive index of liquids. This paper describes the details of the system, which is easy to align and compact, and a series of measurements performed on liquids. An analysis of the accuracy of the method is presented, which is proven to be within one part in .
