HoloPy is a python based tool for working with digital holograms and light scattering.

Development of holopy has moved to github:

Modern documentation of HoloPy is on readthedocts:


HoloPy provides easy tools to:

* Load and visualize images, and associate them with experimental metadata
* Reconstruct 3D volumes from digital holograms
* Do Scattering Calculations:
     - Compute Holograms, electric fields, scattered intensity, cross sections, ...
     - From spheres, clusters of spheres, and arbitrary structures (using DDA)
* Make precise measurements by fitting scattering models (based on the above structures) to experimental data.

HoloPy is intended to support research using holograms, especially soft matter (colloid) research. We hope it will become a standard for processing digital holograms. HoloPy welcomes contributions; join the mailing lists or email us if you would like to help out.

HoloPy is based upon work supported by the National Science Foundation under Grant No. CBET-0747625 and performed in the Manoharan Lab at Harvard University (
