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.

'Shack-Hartmann Wavefront Sensor based on an Industrial Smart Camera

, 2012
Wavefront sensing is important in many optical measurement systems and adaptive optics. The speed of the wavefront sensor determines the achievable temporal resolution of dynamic measurements and the bandwidth of adaptive optics systems.

Artificial Intelligence in Intraoral Scanning: A Narrative Review

Australian Dental Journal, EarlyView.
ABSTRACT Intraoral scanning (IOS) enables the acquisition of three‐dimensional surface models of dental and oral structures, supporting diagnosis, treatment planning and digital workflows. However, many processing steps remain operator‐dependent and time‐consuming. The integration of artificial intelligence (AI) with intraoral scanning (IOS) represents

Patient‐reported outcomes and visual function after four refractive strategies in cataract surgery: A randomized controlled trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate patient‐reported outcome measures (PROMs) and visual function across four groups of public cataract patients: emmetropia, mini‐monovision, monovision with partial‐range of field (RoF) narrow intraocular lenses (IOLs) and patients implanted with partial‐RoF extended IOLs.
