To answer this three sections of literature research are included in which the following subjects will be explored: Spatial/temporal modes/coherence, stellar interferometry and the second order correlation function (g(2)) for thermal light. The insights gained in these sections will be used for two experiments. The first experiment is designed to detect spatial fluctuations, which was achieved by a simple setup involving a double slit and two pinholes. The second experiment, designed to detect temporal fluctuations using the g(2) of a quasi-thermal light source, did not find significant results, which contradicts the results of a simulation of g(2) for thermal light.Show less
