First experiments on diffraction-enhanced imaging at LNLS
(Blackwell MunksgaardCopenhagenDinamarca, 2003)
2D common-offset traveltime based diffraction enhancement and imaging
(Wiley-blackwellHobokenEUA, 2013)
Multiple imaging radiography at LNLS
(ELSEVIER SCIENCE BVAMSTERDAM, 2008)
An analyzer-based X-ray phase-contrast imaging (ABI) setup has been mounted at the Brazilian Synchrotron Light Laboratory (LNLS) for multiple imaging radiography (MIR) purposes. The algorithm employed for treating the MIR ...
Image enhancement by spatial frequency post-processing of images obtained with pupil filters
(Elsevier Science, 2016-06)
The use of apodizing or superresolving filters improves the performance of an optical system in different frequency bands. This improvement can be seen as an increase in the OTF value compared to the OTF for the clear ...
High-resolution imaging of diffractions - A window-steered MUSIC approach
(Soc Exploration GeophysicistsTulsaEUA, 2013)
Coupling between surface plasmon resonance and Sm3+ ions induced enhancement of luminescence properties in fluoro-tellurite glasses
(2017-10-01)
Fluoro-tellurite glasses co-activated with Samarium (Sm3+) ions and silver nanoparticles (Ag NPs) were prepared using melt quenching technique. The nucleation and growth of Ag NPs were controlled by thermal annealing ...
Denisiuk-type reflection holography display with sillenite crystals for imaging and interferometry of small objects
(Elsevier B.V., 2008-02-01)
A novel setup for imaging and interferometry through reflection holography with Bi12TiPO20(BTO) sillenite photorefractive crystals is proposed. A variation of the lensless Denisiuk arrangement was developed resulting in a ...
Dual-surface modification of titanium alloy with anodizing treatment and bioceramic particles for enhancing prosthetic devices
(Springer, 2017-04)
In this work, two strategies of surface modification of metallic biomedical implants are presented. An anodizing treatment onto titanium surface to enhance a barrier effect for minimizing corrosion and a bioactivation of ...
