Mutual information-based degrees of coherence of partially polarized light with Gaussian fluctuations.
The spatiotemporal coherence properties of partially polarized light with Gaussian probability distributions are analyzed using the mutual information that is a standard measure of statistical dependence. This approach leads to intrinsic degrees of coherence that have powerful invariance properties and that provide new information in comparison with other recently introduced degrees of coherence.
