Partial Polarization of Optical Beams: Temporal and Spectral Descriptions
A fluctuating, statistically stationary, polychromatic electromagnetic field can, at any instant of time, be regarded as fully polarized but on time average or in the frequency space its state of polarization may be quite different. In this chapter, we analyze the variations between the degrees of polarization of optical beams in time and frequency domains. We point out the origins of the differences and illustrate the physical consequences by several examples.
