On the conditional equivalence of phase retrieval algorithms
Jakob Schroeder, Andreas Döpp
Phase retrieval - recovering a complex-valued field from intensity measurements - is typically solved using variants of the Gerchberg-Saxton (GS) algorithm, understood as alternati…
Information-Optimal Sensing and Control in High-Intensity Laser Experiments
A. Döpp, C. Eberle, J. Esslinger +5
High-intensity laser systems present unique measurement and optimization challenges due to their high complexity, low repetition rates, and shot-to-shot variations. We discuss rece…
Information-optimal measurement: From fixed sampling protocols to adaptive spectroscopy
J. Schroeder, S. Howard, C. Eberle +4
All measurements of continuous signals rely on taking discrete snapshots, with the Nyquist-Shannon theorem dictating sampling paradigms. We present a broader framework of informati…
A Bayesian perspective on single-shot laser characterization
J. Esslinger, N. Weisse, C. Eberle +5
We introduce a Bayesian framework for measuring spatio-temporal couplings (STCs) in ultra-intense lasers that reconceptualizes what constitutes a 'single-shot' measurement. Moving…
Sparse Reconstruction of Wavefronts using an Over-Complete Phase Dictionary
S. Howard, N. Weisse, J. Schroeder +5
Wavefront reconstruction is a critical component in various optical systems, including adaptive optics, interferometry, and phase contrast imaging. Traditional reconstruction metho…
