Intensity Interferometry Experiment, Christy Rose Pedraza

Physics

In this experiment we investigate the correlations in the intensity of diffracted light using an interferometer similar to Hanbury Brown and Twiss’. We use a pseudo-thermal light source composed of a laser and a rotating ground-glass screen with detection by silicon photodiodes. The experimental results agree with the theory that describes the correlation between spatially separated parts of the intensity field.
