Paper Abstract

In this article, I describe a new, inexpensive way to make transparent phase screens. I list available technologies of physical turbulence simulation and describe the transparent phase-plate screens that were produced by the laquer-spray technique and characterized in the laboratory. The spatial spectrum of phase perturbations is a reasonable match to the Kolmogorov law with r0 around 0.5 mm at 0.633 μm over spatial frequencies from 0.75 to 5 mm-1. A turbulence simulator using two such rotating screens and destined for the adaptive optics instrument for the 4.1-m SOAR telescope is described.
