Abstract
Non-interferometric phase-space tomography is used to characterize the spatial coherence properties of scalar quasi-monochromatic partially coherent optical fields. Three sources were investigated and characteristic projections through the correlation functions determined. It was seen that a single-mode fibre-coupled source exhibited a much longer coherence length than a multi-mode fibre-coupled source. Both sources exhibited a high degree of symmetry. A collimated light emitted diode, on the other hand, was shown to have a short spatial coherence length and clear asymmetries were evident.
