- © 2022 IOP Publishing Ltd.In this work, we present an introduction to the field of spatially partial coherent beams, while keeping in mind the transverse structure of an optical field. We look closely at the concept of spatial coherence and show some strategies to deal with it. We work step-by-step with the reader and construct as an example, a partially coherent vortex beam. Finally, using numerical simulations, the richness in structure of a partially coherent field is revealed through its cross-correlation function.
