A new experimental and theoretical method has been presented for measuring the refractive index of liquids and transparent solids. The experimental setup is based on a modified version of the Michelson interferometer employing a rotation stage. This technique allows us the determination of the refractive index of a given liquid (or a transparent sample) accurately to high precision, with an accuracy limited only by the precision in the determination of the rotation angle.
