Abstract

A new technique to generate a spatially varying coherence field, such as a coherence comb using a Dammann grating, is proposed and experimentally demonstrated. The principle of the technique lies with the vectorial van Cittert–Zernike theorem, which connects vectorial source structure with the coherence–polarization of the light. The Dammann grating is encoded into one of the polarization components of the light to shape the vectorial source structure and, consequently, the coherence–polarization of the light. Experimental results on the generation of a spatial coherence comb by the Dammann grating are presented for different orders.
