New approach is proposed for estimating the degree of coherence of optical waves. The possibility of transformation of spatial polarization distribution in measured intensity distribution for estimating the degree of correlation of superposing vector waves linearly polarized at the incidence plane is shown.

Holography is a well-known technique for sensing and displaying real-world three-dimensional (3D) objects. Digital holograms have been successfully displayed on conventional stereoscopic displays allowing research into perception of quality of 3D holographic data. We do know that quality is enhanced if reconstructions of digital holograms are displayed with conventional stereoscopic displays rather than with a regular two-dimensional (2D) screen. However, it is not known how different attributes (e.g. noise, blur, and perceived depth) and the viewer's subjective perception of quality are related. In this study, we show how 13 viewers evaluated these attributes and the visual quality of five holograms displayed stereoscopically.

We study the time evolution of the instantaneous polarization state, i.e., the polarization dynamics of random, statistically stationary three-dimensional electromagnetic fields. Two intensity-normalized polarization correlation functions which characterize the similarity of the polarization state at two times are presented. One of them is based on the generalized instantaneous Poincaré vectors and the other on the Jones vectors. We discuss the basic properties of the correlation functions and define a polarization time as a time interval over which the state of polarization does not significantly change. If the field obeys Gaussian statistics the polarization correlation functions are expressible in terms of certain second-order, measurable parameters characterizing the partial polarization and partial coherence of the field. We exemplify the formalism with a uniformly partially polarized, temporally Gaussian correlated field, and with the field at the intersection of three orthogonally propagating, linearly polarized and mutually correlated beams. The results are expected to find use in applications where the polarization fluctuations of a three-dimensional field play an important role.
