Fluorescent‐target imaging and real‐time beam diagnostics at the High Energy Photon Source

Journal of Synchrotron Radiation, EarlyView.
A fluorescent‐target imaging and real‐time beam diagnostic platform has been developed for the High Energy Photon Source (HEPS), integrating synchronized multi‐camera acquisition within the Experimental Physics and Industrial Control System (EPICS) areaDetector framework, online beam‐parameter extraction, and Mamba Data Worker enabled data management ...

Robust Image-Based Wavefront Sensing

, 2011
Several planned future optical systems, such as the James Webb Space Telescope (JWST), rely on image-based wavefront sensing for alignment, testing, and control of optical surfaces during operation. The focus of this work is on characterizing the effects

Diffractive wavefront correction for Fe L‐edge spectroscopy on the meV scale

Journal of Synchrotron Radiation, EarlyView.
We propose an aberration‐corrected, wavelength‐dispersive instrument for soft X‐ray spectroscopy at an energy‐resolving power of (5–6) × 104, designed for, for example, resonant inelastic X‐ray scattering at synchrotron beamlines or X‐ray free‐electron lasers.We propose a wavelength‐dispersive instrument for high‐resolution soft X‐ray spectroscopy at ...

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.

Wave Tracing: Generalizing The Path Integral To Wave Optics

Computer Graphics Forum, EarlyView.
Abstract Modeling the wave nature of light and the propagation and diffraction of electromagnetic fields is crucial for the accurate simulation of many phenomena, yet wave simulations are significantly more computationally complex than classical ray‐based models.
