Young’s double-slit experiment with twisted Gaussian Schell model beam
Year: 2025
Type: article
Abstract: We theoretically investigate the spatial coherence properties of a partially coherent beam described by the twisted Gaussian Schell-model (TGSM) after passing through a Young's double-slit configuration. The presence of a twisted phase induces coupling between the transverse coordinates parallel and perpendicular to the slits, establishing nontrivial spatial correlations across the observation plane. Analytical expressions for four types of mutual coherence functions are derived and analyzed under varying twist phase conditions. The results demonstrate that the twisted phase significantly modifies the coherence structure of the beam. This work provides a simple and feasible experimental scheme for detecting and characterizing twisted phase effects in partially coherent light beams.
