Provable and Robust Wavefront Sensing via Self-Reference Interferometry

Provable and robust optical wavefront sensing via self-reference interferometry. We use a spatial light modulator in a 4f configuration with a co-prime shift design, enabling graph-based phasor propagation with provable guarantees. Full phase recovery from very few measurements.
