Wavelength-dependent speckle scattering phenomena in birefringent materials with rough interfaces

Surface polarization scattering is investigated based on the coherence matrix for the electric field scattered from a birefringent material with a random interface between its surface and air. However, most studies of speckle statistics for wavelength dependence have ignored its polarization properties which arise from the vector nature of the electromagnetic field. In this paper, we examine the influence of wavelength changes in greater detail. The most fundamental effects of a change in wavelength on the spatial structure of polarization speckle have been explored to understand the underlying mechanism of the rough surface in birefringent materials scattering phenomena for the electric field with random states of polarization. In order to analyze the wavelength dependence of polarization speckle statistics, free-space propagation is studied. We considered using two separate wavelengths in the illumination. Under the right conditions, to be derived, this can reduce speckle contrast.
