Fundamentals of Optics and Radiometry for Color Reproduction

Roger Hersch, Mathieu Hébert, Patrick Emmel

Visual appearance of objects comes from the interpretation by the human visual system of a light signal issued from the objects. Describing or predicting appearance is therefore a question of light and requires notions about light propagation and measureme ...

Effect of a noisy driving field on a bistable polariton system

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol, Hadis Abbaspour, Grégory Chilpéric Sallen

We report on the effect of noise on the characteristics of the bistable polariton emission system. The present experiment provides a time-resolved access to the polariton emission intensity. We evidence the noise-induced transitions between the two stable ...

Translating Head Motion into Attention - Towards Processing of Student’s Body-Language

Pierre Dillenbourg, Lukasz Kidzinski, Mirko Raca

Evidence has shown that student's attention is a crucial factor for engagement and learning gain. Although it can be accurately assessed ad-hoc by an experienced teacher, continuous contact with all students in a large class is difficult to maintain and re ...

A dynamic operation of a PIN photodiode

Alexander Tagantsev, Maher Kayal, Adil Koukab, Serguei Okhonin, Maxim Gureev, Alexander Kvasov, Marc Pastre, Denis Sallin

Traditionally, photodiodes operate at static reverse bias, and incident light intensity is obtained from the relatively week photocurrent. In this paper, we introduce a different concept of photodiode function: the photodiode is used in a dynamic regime wh ...

New Cadanav methodology for quantitative rock fall hazard assessment and zoning at the local scale

Vincent Labiouse, Jacopo Maria Abbruzzese

Rock fall hazard zoning is a challenging yet necessary task to be accomplished for planning an appropriate land use in mountainous areas. Methodologies currently adopted for elaborating zoning maps do not provide satisfactory results though, due to uncerta ...

Compact High-Performance Continuous-Wave Double-Resonance Rubidium Standard With 1.4 x 10(-13) tau(-1/2) Stability

Anja Skrivervik, Francesco Merli, Camillo Stefanucci

We present our studies on a compact high-performance continuous wave (CW) double-resonance (DR) rubidium frequency standard in view of future portable applications. Our clock exhibits a short-term stability of 1.4 x 10(-13) tau(-1/2), consistent with the s ...

Retrieval of vertical particle concentration profiles by optical remote sensing: a model study

Alfred Johny Wüest

Water-leaving radiance is subject to depth variability of the water constituents. The optical penetration depth is strongly dependent on the wavelength λ, which allows to retrieve a non-uniform vertical profile of an optically-active constituent CTSM(z) fr ...

A deep-blue emitting charged bis-cyclometallated iridium(III) complex for light-emitting electrochemical cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti

We report here a new cationic bis-cyclometallated iridium(III) complex, 1, with deep-blue emission at 440 nm and its use in Light-emitting Electrochemical Cells (LECs). The design is based on the 2',6'-difluoro-2,3'-bipyridine skeleton as the cyclometallat ...

Quantitative mapping of fast voltage pulses in tunnel junctions by plasmonic luminescence

Klaus Kern, Markus Etzkorn, Christoph Grosse

An optical read-out technique is demonstrated that enables mapping the time-dependent electrostatic potential in the tunnel junction of a scanning tunneling microscope with millivolt and nanosecond accuracy. We measure the time-dependent intensity of plasm ...
