Abstract

Simulating the effects of atmospheric turbulence on optical imaging systems is an important aspect of understanding the performance of these systems. Methods exist for making random draws of phase screens which arise from the Kolmogorov spectrum. In this paper we describe and demonstrate a method for creating random draws of phase screens which would arise from the von Karman spectrum. This phase screen generation technique can be used to make random draws of properly correlated stacks of phase screens shifted in time with respect to each other, and to create properly correlated phase screens arriving from different directions at the telescope pupil. In this paper we present the basic theory and implementation of this phase screen generation technique. Phase screen generation and point spread function results are presented.
