Abstract

Optical coherence theory traditionally deals with the properties of randomly fluctuating fields over long time averages. For certain applications (such as optical communications) and special beam classes (such as vortex beams), however, the averaging process can obscure important physical aspects of the field behavior. We demonstrate a new method of simulating partially coherent fields of nearly arbitrary spatial and temporal coherence. Over sufficiently long time intervals, these simulations produce the expected average properties. The results are used to gain insight into the propagation properties of partially coherent fields through atmospheric turbulence.
