Motivated by a recently predicted phenomenon, the geometric spin Hall effect of light (gSHEL) at polarizing interfaces [1], we investigate the action of a real polarizer. In this work, we study a commercial polymer film polarizer and compare our experimental findings with a well-known projecting polarizer model [2].
To this end, we rotate and tilt our polarizer around the horizontal and vertical axes and measure the Müller Matrix for a multitude of configurations. The Müller Matrix describes, how a sample effects the state of polarization of a light beam transmitted across it.
We specifically adapt the polarizer model to the case of absorbing polarizers. We show that this modified model is in good agreement with our experimental data.
Finally we present a setup designed to measure the position of a light beam transmitted across a tilted polarizer. This setup allows a direct measurement of the gSHEL using our
