j Wavefront sensing and guiding units for the Large Binocular Telescope

, 2008
The Large Binocular Telescope (LBT) will see first light with a single primary mirror in January 2003. It will be equipped with fully adaptive secondary mirrors from the beginning as well as a complete on-axis wavefront sensing and tip-tilt guiding ...

Polynomial‐shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
A shaped electrode design for lithium niobate adaptive X‐ray mirrors connects actuator degrees of freedom to specific polynomial orders, enabling general shape control and the correction of defocus, coma and fourth‐order aberrations with a limited number of inputs.For adaptive mirrors on X‐ray beamlines and optical systems, we describe a strategy for ...

Mirror alignment by particle swarm optimization for synchrotron radiation beamlines

Journal of Synchrotron Radiation, EarlyView.
A particle swarm optimization‐based automated two‐mirror alignment method was developed to restore high‐flux beams in approximately 5 min, and its 15 month deployment demonstrated its robustness and reliability.This article proposes a particle swarm optimization (PSO)‐based automated mirror‐alignment methodology that enables the utilization of high ...

From analytical to data‐driven: multi‐method optimization of a bendable mirror system for dynamic focusing

Journal of Synchrotron Radiation, EarlyView.
A small‐radius‐of‐curvature bendable mirror system is developed for dynamic focusing in X‐ray free‐electron laser and synchrotron radiation beamlines, and a transfer‐learning neural‐network and differential‐evolution framework is used for force‐to‐shape modeling and inverse optimization.
