Background and Aims: Biomolecules' optical and nonlinear optical properties are widely used for different medical diagnoses and applications in biophotonic devices. These properties are essential in studying biological processes in living tissues. Aside from biomolecules' linear optical characteristics, their nonlinear optical characteristics have lately been considered. Materials and Methods:...

Nonlinear refractive index, n of an undoped z-cut photorefractive LiNbO3 crystal has been investigated here by the Z-scan technique using a continuous wave (cw) laser beam from a multiline argon-ion laser. Here both the sign and magnitude of the measured n are considerably different from the reported z-scan result in LiNbO3 obtained with picoseconds pulsed laser at 532 nm but in good agreement ...

Rekonfigurierbare Scan-Netze, z. B. entsprechend IEEE Std. P1687 oder 1149.1-2013, ermöglichen den effizienten Zugriff auf On-Chip-Infrastruktur für Bringup, Debug, Post-Silicon-Validierung und Diagnose. Diese Scan-Netze sind oft hierarchisch und können komplexe strukturelle und funktionale Abhängigkeiten aufweisen. Bekannte Verfahren zur Verifikation von Scan-Ketten, basierend auf Simulation u...

In this study, the nonlinear optical properties and optical limiting performance of the silver nanoparticles (AgNPs) in distilled water are investigated. The nonlinear absorption coefficient of the colloid is measured by the Z-scan technique. The optical limiting behavior of the AgNP suspension is investigated under exposure to nanosecond laser pulses at 532 nm. The results show that nonlinear ...

PURPOSE A drawback of time-resolved 3-dimensional phase contrast magnetic resonance (4D Flow MR) imaging is its lengthy scan time for clinical application in the brain. We assessed the feasibility for flow measurement and visualization of 4D Flow MR imaging using Cartesian y-z radial sampling and that using k-t sensitivity encoding (k-t SENSE) by comparison with the standard scan using SENSE. ...

The desCribed architecture is based on a fusion of scan-line rendering and the conventional z-buffer algorithm. The frame buffers of several z-buffer engines are modified to scan out z-values as well as color values. Multiplexing devices combine the z/color streams from each pair of frame-buffers. These z/color streams are then combined by further multiplexers, creating a binary tree that funne...

Given a specific image processing task and an image, its effectiveness is influenced by proximity driven properties captured in the image scan. One could exploit this effect and maximize the performance by adapting the scan and/or suitably adjusting the original operator. This two part sequel explores the balance between the effort required in scan adaptation and operator reformulation. The def...
