Comparison of Algorithms for Simulating Partially Coherent Systems

The theory of partial coherence is a significant part of Fourier optics, which has been utilized in numerous areas and applications. Therefore, the simulation of partially coherent systems is important for the system analysis and design of optical signal processing and other applications. Therefore, it is useful to identify the differences and strengths of existing simulation methods. In this paper, we compared three partially coherent field simulation algorithms including the random screen, superposition, and coherent mode decomposition methods based on their simulation results. Finally, we identified the optimal usage scenarios for each algorithm.
