The Pristine survey II: A sample of bright stars observed with FEROS

Extremely metal-poor (EMP) stars are old objects formed in the first Gyr of the Universe. They are rare and, to select them the most successful strategy has been to build on large and low-resolution spectroscopic surveys. The combination of narrow- and bro ...

Design, simulation, and quality evaluation of micro-optical freeform beam shapers at different illumination conditions

Hans Peter Herzig, Daniel Infante Gómez

A design method to generate thin micro-optical freeform (MOF) beam shapers by clipping or wrapping an original and much thicker freeform surface is provided. MOF elements are situated at the border between refractive and diffractive optical elements. The i ...

Ultrasensitive 1D field-effect phototransistors: CH3NH3PbI3 nanowire sensitized individual carbon nanotubes

László Forró, Endre Horvath, Richard Gaal, Bálint Náfrádi, Massimo Spina, Eric Joseph Bonvin

Field-effect phototransistors were fabricated based on individual carbon nanotubes (CNTs) sensitized by CH3NH3PbI3 nanowires (MAPbI(3)NWs). These devices represent light responsivities of R = 7.7 x 10(5) A W-1 under low-lighting conditions in the nW mm(-2) ...

Self-Tracking Solar Concentrator Device

Jacques-Edouard Moser, Christophe Moser, Volker Günter Zagolla

A device for self-tracking a light source, including a focusing optical device configured to focus incoming light to a focal spot, an adaptive device configured to reflect the light of the focal spot and arranged to provide for a phase change at an area of ...

Flat lensless phase imager

Christophe Moser, Manon Rostykus

Lensless imaging refers to an imaging technique which requires no imaging element between the light transmitted by the sample and the camera. This configuration enables designing compact devices. In the visible range, it is mainly investigated for microsco ...

Gaze Responsive Visual Comfort: New Findings On Gaze Behaviour In A Daylit Office Space In Relation To Glare

Marilyne Andersen, Jan Wienold, Mandana Sarey Khanie

Using a newly developed gaze-driven methodology for discomfort glare assessments, we studied gaze behaviour in different glare conditions. The study was done in a series of experiments where gaze behaviour of the participants were recorded using eye-tracki ...

Glare Caused By Contrast Between Task And Immediate Surround: An Evaluation Of Luminance Distribution In The Field Of View

Marilyne Andersen, Jan Wienold, Peter Hansen, Mandana Sarey Khanie

Luminance ratios have historically been used to assess glare. Using data from a previous experiment, this exploratory study investigates the relationship between luminance variations in the field of view (FOV), measured as luminance ratios, and glare sensa ...

Evidence for Rhythmicity Pacemaker in the Calcification Process of Scleractinian Coral

Anders Meibom, Jaroslaw Hubert Stolarski, Isabelle Domart-Coulon

Reef-building scleractinian (stony) corals are among the most efficient bio-mineralizing organisms in nature. The calcification rate of scleractinian corals oscillates under ambient light conditions, with a cyclic, diurnal pattern. A fundamental question i ...
