Young’s Interference Experiment with Partially Coherent Light

The double-slit interference experiment was originally conducted by Thomas Young in the early 1800s. It shows the wave-like nature of light and serves as an important technique for spatial coherence measurements. We reproduce Young’s experiment in VirtualLab Fusion, with both a single point source and an extended source. We investigate in particular the coherence properties of the extended source by checking the change in the contrast of the interference fringes.

Young's Interference Experiment

In VirtualLab Fusion, we reproduce the famous Young interference experiment, and check the influence of slit width, slit distance, as well as the effect of employing an extended source.
