Measuring the Stokes polarization parameters

Abstract

The Stokes formulation for representing polarized light is discussed along with the classical measurement method for determining the Stokes polarization parameters. The limitations of this method are noted, and we consider the rotating quarter-waveplate method, which avoids the limitations of the classical method and allows a curve fitting algorithm to be used to determine the Stokes parameters. The quarter-waveplate method is attractive because of its accuracy and simplicity and can be implemented in an undergraduate or graduate optics course with a minimum amount of equipment.
