Title  Research of Speckle in the Polarization Characteristics
Modern optical technology increasingly rely on polarized light carry a wealth of information as a means of detection and perception of the material world. The polarization parameters are important degrees of freedom outside of the electromagnetic field intensity, phase, spectral parameters, mainly refers to the proportion of completely polarized component in the polarization of light (total energy) and the polarization state of two aspects. Accurate knowledge of the characteristics of their behavior is a basic prerequisite for effective use of polarization information which makes the polarization parameters from the theoretical level, several laws of the development of polarized light techniques can not be avoided between the title.
The paper start From the theoretical level,  polarization properties of speckle in the use of the application of the Stokes parameters and related formulas and system theory simulation by MATLAB software, resulting in a planar lightwave interference superimposed on the spot vector amplitude fieldthe singular feature points, and the spot in the understanding and analysis, to find the circular polarization feature points, and then analyze the characteristics of circularly polarized distribution of feature points found.

Key words polarization； vector speckle； Stokes parameter； matlab simulation
