Single-shot generalized Hanbury Brown–Twiss experiments using a polarization camera for target intensity reconstruction in scattering media

Abstract

To see through a random light field in real-time, single-shot generalized Hanbury Brown–Twiss experiments using a polarization camera are proposed. The target intensity distribution is obtained from a complex coherence function which is calculated from auto-correlation and cross correlation functions of phase-shifted speckle intensity distributions. The phase-shifted speckle intensity distributions are simultaneously obtained through a strategy of parallel phase-shifting digital holography. Experimental results show that the proposed method can image a moving object in a random light field using a measured complex coherence function through the van Cittert–Zernike theorem.
