TurbulenceSim_v1Public

This repository contains the code for the following paper:

Nicholas Chimitt and Stanley H. Chan "Simulating anisoplanatic turbulence by sampling intermodal and spatially correlated Zernike coefficients," Optical Engineering 59(8), Aug. 2020

How to use:

There are two example files provided, the "Example_1_full.py" file, and the "Example_2_tiltonly.py" files. The tilt-only file is simpler, yet the Example_1_full offers the full version of the simulator described in our work. The Example_1_full is a documented typical usage case.
The "TurbSim_v1_main.py" file forms the main body of the functionality, calling upon "Motion_Compensate.py" and "Integrals_Spatial_Corr.py" as needed. The functions therein are documented to help in their interpretability.

Packages included

We use a function to simplify some indexing "nollToZernInd" (Tim van Werkhoven, Jason Saredy; https://github.com/tvwerkhoven/libtim-py/blob/master/libtim/zern.py)

We would also encourage those interested in this simulator to use the Python version, which offers more flexibility and ease of use than its MATLAB counterpart.
