“…Digital holographic technique is used to determine complex amplitude and polarization on surface of the object in single shot. Single shot techniques for polarization imaging has drawn attention in recent years [3][4][5][6][7]. Recently polarization imaging of 3D objects using onaxis phase shifting digital holography is demonstrated [8].…”

In this paper, we propose and demonstrate Stokes holography for recording and reconstructing a object using polarization fringes. Reconstruction is carried out by scattering the polarization fringes through ground glass, and replacing the ensemble averages by space averages of the randomly scattered Gaussian field. Object encoded into polarization fringes are reconstructed into their corresponding elements of generalized Stokes parameters. Experimental and numerical results of a point object reconstruction are presented.

Effect of residual phase gradients in optical null interference

A scheme to study the effect of residual phase gradients in an optical interference between two out-of-phase Gaussian beams is proposed. In a Sagnac interferometer configured to provide a null output, a variable linear phase swept across the null point unfolds an optical field rotation due to an apparently negligible residual phase gradient present orthogonal to the linear phase sweep. As the optical beam that rotates around its propagation axis carries orbital angular momentum, the experimental results presented in this Letter could provide an insight into the momentum change associated with the energy redistribution in the fundamental phenomenon of optical interference.
