Phase screen-based wave optics simulations are a fundamental tool used by researchers seeking to understand the effect of atmospheric turbulence on laser beam propagation and imaging. Most wave optics packages are either themselves proprietary or rely on expensive, proprietary software packages. We have developed WavePy, a wave optics package based in the open-source Python programming environment. Using WavePy we have been able to produce turbulence-corrupted imagery similar to those observed by ground-based telescopes imaging space objects. We have also simulated plane wave and spherical wave propagation through uniform turbulence volumes. In both cases, we found the execution time between the WavePy and MATLAB versions to be similar under certain circumstances.
