The ability to simulate atmospheric turbulence is a crucial part of enabling adaptive optics technology to function and evolve. We report a new technique of creating phase plates developed at the Laboratory for Adaptive Optics (LAO) which involves the application of clear acrylic paint onto a transparent substrate. Results of interferometric characterization of these plates is described and compared to Kolmolgorov statistics. These plates have been successfully used in the Multi-Conjugate Adaptive Optics (MCAO) testbed and as part of the Villages (Visible Light Laser Guidestar Experiments) calibration system.
