Welcome to Beampy's documentation!

Beampy is a python module based on the Beam Propagation Method¹ 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 thesis², and later modified at the FEMTO-ST institute of the Université de Franche-Comté and at the LMOPS laboratory³ of the Université de Lorraine.

Installation

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

Starting the software

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.
