Abstract

We present a novel method to extract phase information of a diffuse object illuminated by linearly polarized light. This method involves the combination of off-axis digital holography (DH) and the transport of intensity equation (TIE) where the hologram is recorded with two reference waves that have orthogonal linear polarization states, simultaneously interfered with the object beam illuminated with a random linear polarization state. Thus, phase information of both polarization states can be obtained. This technique of using TIE along with DH reconstruction using Fresnel propagation has been shown as an effective phase unwrapping technique to uncover either the phase of transmissive objects or the topography of contoured objects.
