Fig. 7

Simulations of the fringes for different source sizes and the indicated values of system visibility (vis). Left: Simulation for a fringe size of 1000 \({\upmu {\textrm{m}}}\). Middle: Simulation for a fringe size of 800 \({\upmu {\textrm{m}}}\). Right: Simulation for a fringe size of 500 \({\upmu {\textrm{m}}}\). With decreasing fringe size, the source size penalty increases as expected from Eq. 3. The fringes show examples from which the visibility simulation points from Fig. 6 were obtained.
