Multi-spectral characteristics of polarization retrieve in various atmospheric conditions

We have investigated the multi-spectral characteristics of polarization reconstruction after the incident polarized light traveled a long distance in various atmospheric conditions. In order to retrieve the original polarization information of incident light from the scattered optical field, a novel polarization retrieve (PR) method is established by using the effective Mueller matrix based on Monte Carlo (MC) algorithm, and an existing polarization maintaining (PM) method which is the usual way in quantum communication is also exploited for comparison. It is demonstrated that the original polarization states of the initial field can be reconstructed accurately by PR method, and the influence factors of PR method are related to wavelength, particle size and particle number density. Furthermore, the simulated results show that the infrared light source can reduce the loss of polarization information effectively, and our PR method not only is more applicable to disordered media, such as low altitude atmosphere with larger size of aerosols and other particles, but also has a higher robustness.
