Description
The coherence of optical fields is a defining factor in how they are represented and characterised, in this work we employ the Wigner Distribution Function (WDF) for a generalized optical field characterisation method. We characterize a Gaussian-Schell model partially coherent beam by determining the beam width, divergence, curvature and beam quality factor of the pure field from the mutual correlation function and its corresponding WDF. The beam is digitally encoded using an SLM. The WDF is a space-frequency representation and in the spatial domain, we find comparable accuracy between the parameters obtained using the pure optical field and the WDF.
