Abstract
We present an experimental setup to generate partially coherent Ince-Gaussian beams. The partially coherent field is constructed using a rotating ground glass disk to reduce the spatial coherence of a laser source and digital holograms. Our results show that the cross correlation function of these beams inherit properties of their spatial structure. The experimental cross correlation function is measured by means of a well known wavefront folding interferometer, which allows us to characterize the properties of the beam. The comparison between theoretical and experimental results yields excellent agreement.
