Ghost ellipsometry using classical light

This thesis presents a new interferometric technique for the measurement of ellipsometric information by the means of classical ghost imaging. The technique relies on the use of light from a classical, spatially incoherent source with Gaussian statistics. The standard ghost-imaging configuration is modified for reflection measurements and polarizers are added to control the state of polarization of the beams. The results of the classical ellipsometer are also compared to those obtained from its quantum counterpart, the so-called entangled twin-photon ellipsometer. This ellipsometer uses polarizationentangled twin photons, generated by process of spontaneous parametric down-conversion. In this thesis we show that entanglement is not needed for ghost polarimetry.
