Abstract
We have constructed an ellipsometer capable of rapid polarization measurements based on two photoelastic modulators. It is capable of simultaneously measuring all elements of the Stokes vector on a 10-ms time scale, allowing for a complete polarization analysis including any depolarization that may occur at rough and inhomogeneous surfaces. We overcome the traditional challenges associated with electro-optic modulators through a novel scheme for the calibration of the retardation amplitude and a means for precisely controlling the temperature of the optics. This instrument is therefore especially suited for studying the real-time adsorption of proteins from solution onto solid surfaces. We provide a demonstration of bovine serum albumin adsorption from saline solution onto a hydrophilic silica surface.
