We have derived the relationship between polarization and intensity fluctuations due to point sources. In the case of a Poisson distribution of a population with uniform evolution properties and constant polarization degree, polarization fluctuations are simply equal to intensity fluctuations times the average polarization degree. Conservative estimates of the polarization degree of the classes...

The performance of optical components can have significant dependence on polarization, as with the difference between TE and TM polarization in planar devices like AWG and SOA. Determination of the optical properties for the principal states of polarization can be needed, for instance to determine the polarization dependent wavelength of a bandpass filter. It can be complicated to adjust instru...

The polarization of radar antenna vary with scan direction. This phenomenon is called Spatial Polarization Characteristic (SPC) of antenna. Based on the SPC of single polarized antenna, a novel polarization estimation method is established. Comparing with the traditional estimation method, this one has the following advantages: (i) It does not need dual-polarization channels to estimate the sig...

In this paper, we suggest a framework for the analysis of ethnic polarization. This framework allows for the measurement of ethnic or religious polarization. We apply our measure to Ivory Coast and find a surprising result as the ethnic polarization decreased in years preceding the conflict in the country. However, further decomposition of the ethnic polarization index allows us to understand b...

Polarization-encoded imaging consists of the distributed measurements of polarization parameters for each pixel of an image. We address clustering of multidimensional polarization-encoded images. The spatial coherence of polarization information is considered. Two methods of analysis are proposed: polarization contrast enhancement and a more-sophisticated image-processing algorithm based on a M...

With polarization of the cosmic microwave background (CMB) now detected, and confirmed by several independent experiments, the next goal is to characterise accurately its statistical properties. In these lecture notes we review the physical motivation for pursuing CMB polarization, and the basic statistical properties of the polarization fields. We then discuss some of the key aspects of the an...
