Intensity-only measurement of partially uncontrollable transmission matrix: demonstration with wave-field shaping in a microwave cavity
Philipp del Hougne, Boshra Rajaei, Laurent Daudet +1
Transmission matrices (TMs) have become a powerful and widely used tool to describe and control wave propagation in complex media. In certain scenarios the TM is partially uncontro…
Robust phase retrieval with the swept approximate message passing (prSAMP) algorithm
Boshra Rajaei, Sylvain Gigan, Florent Krzakala +1
In phase retrieval, the goal is to recover a complex signal from the magnitude of its linear measurements. While many well-known algorithms guarantee deterministic recovery of the…
Fast phase retrieval for high dimensions: A block-based approach
Boshra Rajaei, Sylvain Gigan, Florent Krzakala +1
This paper addresses fundamental scaling issues that hinder phase retrieval (PR) in high dimensions. We show that, if the measurement matrix can be put into a generalized block-dia…
