Wavefront sensor based on angle selectivity of an optical filter

The effectiveness of free-space laser communications is limited due to wavefront deformations caused by atmospheric optical turbulence. To determine these deformations, we propose a wavefront sensor that utilizes the angular selectivity of an optical ...

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.

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

Multipoint Pacing Versus Cardiac Resynchronization Therapy in Heart Failure: A Systematic Review and Meta‐Analysis

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Multipoint pacing (MPP) delivers sequential stimuli from multiple left‐ventricular electrodes, potentially improving cardiac resynchronization therapy (CRT) response versus conventional biventricular pacing (BiV). We performed an updated systematic review and meta‐analysis to synthesize contemporary evidence.

Heterodyne Wavefront Sensor for High-Speed and Low-Light Applications

Accurate and fast wavefront sensing is crucial to ensure real-time correction of turbulence in laser propagation through the atmosphere. We present a device for this purpose which we call the heterodyne wavefront sensor. It works by frequency shifting an
