Common-path ghost imaging through complex media with dual polarization.

Abstract

The performance of ghost imaging (GI) is severely compromised by dynamic and complex scattering media in free space. In this Letter, we design a common-path GI (CPGI) setup with dual polarization in complex environments. The s-light and p-light with mutually perpendicular polarization states are generated and overlap in free space in the designed optical path to correct a series of dynamic scaling factors induced by the complex scattering media. Experimental results demonstrate that the proposed method is highly robust and can achieve high imaging quality in complex media. Compared to previous schemes, the proposed method adopts a simplified optical setup and realizes high-quality GI in complex and dynamic scattering environments without extra algorithms in order to promote the wider application of GI.
