Minimal code to perform phase retrieval on LightOn OPUs

Phase retrieval for LightOn OPUs

This repository contains an implementation by our engineer Luca Tommasone of Fast Optical System Identification by Numerical Interferometry by Sidharth Gupta, Rémi Gribonval, Laurent Daudet, Ivan Dokmanić.

Requirements

The requirements are contained in requirements.txt. Install with pip install -r requirements.txt

Running the code

The usage example is in the Jupyter notebook phase_retrieval_minimal.ipynb.

Access to Optical Processing Units

To request access to LightOn Cloud and try our photonic co-processor, please visit: https://cloud.lighton.ai/

For researchers, we also have a LightOn Cloud for Research program, please visit https://cloud.lighton.ai/lighton-research/ for more information.
