Predicting Monochrome Color Transmittance Spectra of Electrophotographic Prints

Roger Hersch, Patrick Emmel, Safer Mourad

We create a computer based numerical model to predict the color spectra of printed patches on dry toner electrophotographic printers. The goal of this research is to obtain a simplified model describing the input-output behavior of the printers based on th ...

Temperature dependence of optical properties of h-GaN films studied by reflectivity and ellipsometry

Nicolas Grandjean

Spectroscopic ellipsometry (SE) carried out at 300 K together with reflectivity measurements performed from 5 to 300 K are used to determine the temperature dependence of the refractive index of hexagonal GaN films between 360 and 600 nm. The refractive in ...

Towards a color prediction model for printed patches

Roger Hersch, Patrick Emmel

A novel color prediction model is presented which unifies, within a framework based on matrices, the phenomena of surface reflection, light absorption, diffuse light sources, superposition of multiple ink layers, and others ...

The pixel size limit for a holographic memory system

Demetri Psaltis, Wei Liu

Compact holographic memory architecture with phase conjugate readout and diffraction suppression by internal reflection is investigated. The pixel size requirement for a competitive system is determined. The bandwidth of the holographic recording in LiNbO3 ...

Temperature dependence of hexagonal-GaN optical properties below the bandgap

Nicolas Grandjean

First, spectroscopic ellipsometry (SE) is carried out at 300 K together with reflectivity measurements versus temperature from 4 to 300 K, in order to determine the temperature dependence of the refractive index of h-GaN films in the transparent region (35 ...

Pulmonary arterial compliance in dogs and pigs: the three-element windkessel model revisited

Nikolaos Stergiopoulos, Patrick Segers, Nico Westerhof

In six dogs and six weight-matched miniature pigs at baseline and after pulmonary embolization, pulmonary arterial compliance was determined using the pulse pressure method (C(PPM)), the three-element windkessel model (C(WK-3)), and the ratio of stroke vol ...

Determination of the absorption and reduced scattering coefficients of human skin and bladder by spatial frequency domain reflectometry

Hubert van den Bergh, Georges Wagnières

A non-invasive method to measure the optical properties of a turbid medium such as biological tissue is described. To determine the absorption and reduced scattering coefficient, the sample is illuminated with spatially intensity modulated light and the ba ...

On the wave transmission and reflection properties of stenoses

Nikolaos Stergiopoulos, Jean-Jacques Meister

This study is concerned with the wave reflection properties of arterial stenoses. Two theoretical models have been developed for deriving the reflection coefficient: a linear model resulting from the linearization of the pressure drop-flow equation and an ...

On the influence of elevated strike objects on the lightning return stroke current and the distant electric field

Marcos Rubinstein

Measurements of return stroke currents on instrumented towers reveal the existence of reflections at the tower bottom and top. In the paper, the effects of the reflections on both measured currents and the original lightning electromagnetic fields are disc ...

Polaritons In High Reflectivity Microcavities - Semiclassical And Full Quantum Treatment Of Optical-Properties

Vincenzo Savona, Paolo Schwendimann

We present a comparison between the semiclassical and the full quantum descriptions of optical properties of quantum wells (QWs) in semiconductor microcavities. The semiclassical theory, which is based on a nonlocal treatment of the optical response of a s ...
