Zoomable telescope by rotation of toroidal lenses.

A novel type of a continuously zoomable telescope is based on two pairs of adjacent toroidal lenses ("saddle lenses") in combination with standard optical components. Its variable magnification is adjusted by a mere rotation of the four saddle lenses around the optical axis. This avoids the necessity of classical zoom systems to shift multiple lenses along the longitudinal axis of the setup. A rotationally tunable pair of saddle lenses consists of two individual saddle lenses (also known as quadrupole lense...


Wide field-of-view crossed Dragone optical system using anamorphic aspherical surfaces.

A side-fed crossed Dragone telescope provides a wide field of view. This type of telescope is commonly employed in the measurement of cosmic microwave background polarization, which requires an image-space telecentric telescope with a large focal plane over broadband coverage. We report the design of a wide field-of-view crossed Dragone optical system using anamorphic aspherical surfaces with correction terms up to the 10th order. We achieved a Strehl ratio larger than 0.95 over 32×18 square degrees at 150...

Determination of the optical turbulence parameters from the adaptive optics telemetry: critical analysis and on-sky validation.

It has been demonstrated by several authors that the optical turbulence parameters associated with a given adaptive optics (AO) run-the seeing angle and outer scale-can be determined from a statistical analysis of the commands of the system's deformable mirror (DM). The higher the accuracy on these parameters, the more we can make use of them, allowing for instance a better estimation of the seeing statistics at the telescope location or a more accurate assessment of the performance of the AO system. In the...

Ritchey-Common sparse-aperture testing of the Giant Steerable Science Mirror.

The Giant Steerable Science Mirror (GSSM) is the tertiary mirror of the future large telescope, the Thirty Meter Telescope. However, the mirror is too large to be tested using only one aperture, and using many apertures will increase the cost of testing. To accomplish testing at a low cost, the number of apertures should be reduced. The Ritchey-Common (R-C) testing method, commonly used for testing large flat surfaces, uses only a reference spherical mirror and avoids the use of large planar interferometers...

Towards the risk of Yellow Fever transmission in Europe.

Yellow fever (YF) is an emerging expanding fatal arboviral disease that has been imported at least six times in Europe during the first half of 2018, while only seven travel-associated YF cases have been reported in the last 20 years, and none from Brazil. YF has a history of transmission in Europe which could become recurrent considering the wide globalization of competent vectors. This article argues that epidemiological current changes put Europe at risk of YF transmission. Risk assessment and strategies...

Bounding the outcome of a two-photon interference measurement using weak coherent states.

The interference of two photons at a beam splitter is at the core of many quantum photonic technologies, such as quantum key distribution or linear-optics quantum computing. Observing high-visibility interference is challenging because of the difficulty of realizing indistinguishable single-photon sources. Here, we perform a two-photon interference experiment using phase-randomized weak coherent states with different mean photon numbers. We place a tight upper bound on the expected coincidences for the case...

A Pareto approach to resolve the conflict between information gain and experimental costs: Multiple-criteria design of carbon labeling experiments.

Science revolves around the best way of conducting an experiment to obtain insightful results. Experiments with maximal information content can be found by computational experimental design (ED) strategies that identify optimal conditions under which to perform the experiment. Several criteria have been proposed to measure the information content, each emphasizing different aspects of the design goal, i.e., reduction of uncertainty. Where experiments are complex or expensive, second sight is at the budget g...

The removal of DAA restrictions in Europe - one step closer to eliminating HCV as a major public health threat.

Of ∼10.2 million people with chronic HCV infection in Europe, most are living in Eastern Europe (6.7 million) followed by Western Europe (2.3 million) and Central Europe (1.2 million). HCV transmission continues to occur - mainly through injection drug use and to a lesser degree, via nosocomial transmission - in parallel with an increasing HCV-related liver disease burden, the result of an ageing population infected during peak HCV epidemics decades prior. In 2016, the World Health Organization set target...

The evolutionary history of human populations in Europe.

I review the evolutionary history of human populations in Europe with an emphasis on what has been learned in recent years through the study of ancient DNA. Human populations in Europe ∼430-39kya (archaic Europeans) included Neandertals and their ancestors, who were genetically differentiated from other archaic Eurasians (such as the Denisovans of Siberia), as well as modern humans. Modern humans arrived to Europe by ∼45kya, and are first genetically attested by ∼39kya when they were still mixing with...

Personal exposure to radio-frequency electromagnetic fields in Europe: Is there a generation gap?

Exposure to radiofrequency electromagnetic fields (RF-EMF) from mobile communication technologies is changing rapidly. To characterize sources and associated variability, we studied the differences and correlations in exposure patterns between children aged 8 to 18 and their parents, over the course of the day, by age, by activity pattern, and for different metrics of exposure.

Implantable miniature telescope (IMT) for vision loss due to end-stage age-related macular degeneration.

Age-related macular degeneration (AMD) causes progressive and irreversible damage to the retina, resulting in loss of central vision. AMD is the third leading cause of irreversible visual impairment worldwide and the leading cause of blindness in industrialized countries. Since AMD is more common in older individuals, the number of affected individuals will increase significantly as the population ages. The implantable miniature telescope (IMT) is an ophthalmic device developed to improve vision in individu...
