Abstract: Non-ideal light sources, with some spectral width, are used in optical experiments, their properties are reflected in many aspects.The requirements of light source in different experiments are different, in this way it is necessary to consider temporal and spatial coherence of the light.Through modifying models of Young's double slit interference and Michelson's interference, the stability as well as strength of simulation can be enhanced and approached to the real operation.Human-computer interfaces are designed to observe different interferences with certain parameter settings to make adjustment of parameters controllable, which also serves as a direction of multi-factor simulation's development.
