Beampy is a python module based on the Beam Propagation Method [1] used to compute light propagation into a varying refractive index. The light propagation is done by the bpm module. An user interface - done using Qt desginer - allows to control the parameters and display the results.
This project was initiate by Jonathan Peltier and Marcel Soubkovsky during a master university course from the PAIP master of the université de Lorraine, under the directive of Pr. Nicolas Fressengeas.
The bpm core codes are mainly based on a compilation of MatLab codes initialy developed by Régis Grasser during his PhD thesis [2], and later modified at the FEMTO-ST institute of the Université de Franche-Comté and at the LMOPS laboratory [3] of the Université de Lorraine.

The online documentation can be found at https://beampy.readthedocs.io/.
The source code of the whole project can be found at https://github.com/Python-simulation/Beampy/.
The PyPI repository can be found at https://pypi.org/project/beampy/.
This package can be download in a python environment using pip install:
pip install beampy
Or by downloading the github folder and setting beampy as a PYTHONPATH. If so, make sure to download Qt5, matplotlib and numpy by using this command in the docs folder:
pip install -r requirements.txt
To start the Beampy interface, import beampy and start the open_app function:
import beampy beampy.open_app()
Or open direclty the user_interface.py file to launch the interface. Or even open the bpm.py to have a non-based interface version.
