Abstract

We address the problem of the estimation of the degree of polarization from a single intensity image. For that purpose, one considers the case of coherent active imagery that leads to speckle fluctuations and assumes that the measured intensity image corresponds to a fully developed speckle for each polarized component of the electric field. In particular, we determine the Cramer–Rao bound of the degree of polarization estimation and propose to illustrate this result by analyzing the variance of different simple estimators.
