MOI is a computer software to calculate the propagation of mutual optical intensity for partially coherent light through beamline developed by SSRF and APS. It's based on statistical optics. The partially coherent wavefront is described by mutual optical intensity. The propagation of mutual optical intensity through the beamline can be numerically calculated with Fresnel approximation. The mutual optical intensity consists of the full coherent information of the wavefront, including the intensity and the in-plane wave vector at any point, the coherent degree and statistical phase difference between any two points.
