Polarization Changes of Stochastic Spatially and Spectrally Partially Coherent Electromagnetic Pulsed Beams in Turbulent Atmosphere

摘要：

　　Using the coherence theory of non-stationary fields and the method of two-time Fourier transform,the analytical expression for the spectral degree of polarization of stochastic spatially and spectrally partially coherent electromagnetic pulsed beams in turbulent atmosphere is derived,and used to study the polarization changes of stochastic electromagnetic pulsed beams propagating through turbulent atmosphere.The influence of pulse frequency and refraction index structure constant on the spectral degree of polarization is emphasized.It is shown that,in comparison with free-space case,the turbulent atmosphere plays an important role on the distribution of the spectral degree of polarization of stochastic electromagnetic pulsed beams propagating in turbulent atmosphere.The results obtained might find potential application for sensing,imaging and communication through the atmosphere.
