Linear polarization holography
In conventional holography, the hologram is formed by recording the interference fringes of two coherent beams using a photosensitive material. The amplitude and phase information of the original signal wave can be reconstructed correctly when readin.....»»
With TPG Deal, AT&T Moves On From Traditional Video Business
With TPG Deal, AT&T Moves On From Traditional Video Business Many consumers may not realize that DIRECTV is now owned by AT&T, and now they may never need to know. AT&T said today that it will sell 30% of DIRECTV and related AT&T linear video busine.....»»
Scientist captures evidence of dynamic seasonal activity on a Martian sand dune
A Southwest Research Institute (SwRI) scientist examined 11 Mars years of image data to understand the seasonal processes that create linear gullies on the slopes of the megadune in the Russell crater on Mars. In early spring images, captured by two.....»»
Researchers find broad impacts from political polarization

Holography "quantum leap" could revolutionise imaging
A new type of quantum holography which uses entangled photons to overcome the limitations of conventional holographic approaches could lead to improved medical imaging and speed the advance of quantum information science......»»
Ultrasonic Holograms: Who Knew Acoustics Could Go 3D?
Imaging and other medical applications waiting in the wings Although its origins trace back to the 1960s and ‘70s, acoustic holography as a field has been hampered by rampant noise created by widespread reflection and scattering. (Lasers.....»»
Antarctica"s ice melt isn"t consistent, new analysis shows
Antarctic ice is melting, contributing massive amounts of water to the world's seas and causing them to rise—but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years' worth of satellite data indicat.....»»

Scientists use diamonds to generate better accelerator beams
Beam-driven wakefield acceleration approaches are promising candidates for future large-scale machines, including X-ray free electron lasers and linear colliders, as they have the potential to improve efficiency and reduce operation cost......»»
Bloodstained: Ritual of the Night"s Classic Mode is now available
In Classic Mode, protagonist Miriam is tasked with traversing five linear stages, doing battle with common enemies and sub-bosses along the way. The levels and gameplay are said to be inspired by the classic games of yesteryear, and to make things a.....»»
Designing Dirac vortex topological photonic crystal fibres
Optical fibres made of topological photonic crystals allow improved versatility and control across the modes and polarization of light they transmit. Compositionally, photonic crystals contain bandgaps to prevent the passage of light relative to spec.....»»
New model reveals previously unrecognized complexity of oceanic earthquake zones
Researchers from the University of Tsukuba applied seismic data from around the world to build a model of the 2020 Caribbean earthquake. Oceanic transform faults are generally considered to be linear and simple and have been widely used in studies of.....»»
