Abstract
A simple phase-shifted polarimetric scheme to extract light polarization changes induced by the sample in surface plasmon resonance (SPR) sensors is presented. The proposed method is based on the conventional Kretschmann-Raether configuration in the angular diverging beam mode using a single wavelength and a variable liquid crystal retarder. An experimental demonstration was performed using different aqueous solutions of ethylene glycol showing a sensitivity of 118.7deg/refractive-index-unit (RIU) and a detection limit of 1.03×10-7 RIU.
