Research Software

AOModel View on GitHub

Python pip-installable Synthetic Data Generation NumPy/SciPy Parameter Estimation Statistical Modeling Aero-Optics BSD 3-Clause

pip-installable Python package implementing the ReVAR (Re-whitened Vector AutoRegression) algorithm for aero-optic modeling and synthetic phase-screen generation. Unlike traditional physics-based models, this fully automated, data-driven approach learns the spatial and temporal statistics of optical turbulence directly from data. Validated on two measured wind tunnel datasets with worst-case 4% NRMSE on the temporal power spectrum. Includes thorough documentation and reproducible examples.

Install:

pip install aomodel

BoilingFlow View on GitHub

Python pip-installable Synthetic Data Generation NumPy/SciPy Inverse Problems Parameter Estimation Spectral Analysis BSD 3-Clause

pip-installable Python package for boiling flow parameter estimation and anisotropic phase-screen generation. Extends a Fourier-based data synthesis method with novel automated parameter estimation and a spatial-anisotropy extension. Validated on two measured wind tunnel datasets. Includes thorough documentation and reproducible examples.
