In this paper Young's interference experiment is treated as a two-slit diffraction phenomenon. Assume that the two slits are illuminated with partially coherent light, a typical example of which is the Gaussian Schell-Model (GSM) beam. The irradiance distribution, namely, the inference fringe distribution, at the observation screen is studied in detail based on the propagation law of partially coherent light. The dependence of irradiance distribution on the coherence parameter of GSM beams and slit size is analyzed and illustrated numerically.

Keywords: Gaussian Schell-model beam; Young's experiment; irradiance distribution; propagation law of partially coherent light
