Paper Abstract

The Naval Research Laboratory has developed a method for simulating atmospheric turbulence and a testbed that simulates its aberrations using a liquid crystal (LC) spatial light modulator (SLM). This testbed allows the simulation of so-called atmospheric seeing conditions ranging from very poor to very good and different algorithms may be easily employed on the device for comparison. Many models for simulating turbulence often neglect temporal transitions along with different seeing conditions. Using the statistically independent set of Karhunen-Loeve polynomials in conjunction with Kolmogorov statistics in this approach provides a spatial and temporal model for simulating turbulence. An added benefit to using an LC SLM is its low cost; and multiple devices can be used to simulate multiple layers of turbulence in a laboratory environment. Current testing using multiple LC SLMs is under investigation at the Naval Research Laboratory.
