Wide Field-of-View Imaging With Wavefront Coded Diffractive Photon Sieves

IEEE Photonics Journal, 2016
We report a demonstration of a wide field-of-view (FOV) imaging with a wavefront coded diffractive photon sieves. In conventional diffractive photon sieves (or other diffractive optical elements), clear imaging can only be achieved within near-zero FOV ...

Diffractive

, 1995
Elastic photoproduction of J= mesons is analysed using data from 1996 and 1997 corresponding to an integrated luminosity of about R L dt 21 pb 1 . The energy dependence of the total photoproduction cross section is presented and predictions in the ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Study of the Properties of Image Formation by an Optical System Consisting of a Diffractive Lens

Ibn Al-Haitham Journal for Pure and Applied Sciences
Diffractive lenses form images based on the principle of light diffraction, unlike conventional lenses that rely on the phenomenon of refraction to form images.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
