Scattering of non-separable states of light

• We generate beams with non-separable polarization and OAM states.
• We experimentally verify the preservation of non-separability under scattering.
• Preservation is confirmed by measuring degree of polarization and contextual imaging.

We experimentally show that the non-separability of polarization and orbital angular momentum present in a light beam remains preserved under scattering through a random medium like rotating ground glass. We verify this by measuring the degree of polarization and observing the intensity distribution of the beam when projected to different polarization states, before as well as after the scattering. We extend our study to the non-maximally non-separable states also.
