Phase shifting digital holography with the Hanbury Brown–Twiss approach

We report a phase shifting holography for coherence waves in the Hanbury Brown and Twiss approach. This technique relies on the wave nature and interference of the coherence waves in the two-point intensity correlation. Experimentation is carried out by recovery of the complex coherence using phase shifting in the intensity correlation. As an application, imaging of the phase target obscured by a random scattering medium is demonstrated, and the results are presented for three different cases. These results are also compared with imaging of the targets in absence of the scattering medium by a conventional phase shifting digital holography.
