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.....»»
New light sheet holography overcomes the depth perception challenge in 3D holograms
Holography—the use of light projection to display images—can be used to construct holograms, which are three-dimensional structures of light that depict true-to-life objects and scenes. While today's technologies can't yet produce the incredibly.....»»
Multi-foci metalens for spectra and polarization ellipticity recognition and reconstruction
As fundamental properties of light, spectra and polarization carry vital information concerning the propagation of light waves. For example, spectral imaging can reflect the material composition of objects, while polarized imaging contains informatio.....»»
Bringing angular momentum to holograms and metasurfaces
Holography, invented by Gabor, provides an approach for recording and reconstructing the complete information (i.e. intensity and phase) of the light from an object. Since its invention, holographic-related technologies have been widely applied in nu.....»»
Assessing the sea surface temperature relationship in shallow marine waters
In a study published in the journal Science China Earth Sciences, researchers led by Dr. Mengyuan Wang (School of Marine Sciences, Sun Yat-sen University) proposed a non-linear regression of UK'37–SST for samples collected from the specific environ.....»»
A new approach to measuring and understanding multidirectional polarization
Germany, India, Mexico, and Spain. As multiparty democracies, these countries present a more complex picture of what brings people together—or divides them. Using social media data, a group of researchers proposes a novel approach to measuring pola.....»»
Bees follow linear landmarks to find their way home, just like the first pilots
Scientists have shown that honeybees retain a memory of the dominant linear landscape elements in their home area like channels, roads, and boundaries. When transported to an unfamiliar area, they seek out local elements of this kind, compare their l.....»»
Roads and power lines put primates in danger: South African data adds to the real picture
About 25 million kilometers of new roads are expected to be built around the world by 2050. Along with power lines and railways, roads cut through the landscape everywhere, disrupting ecosystems. This linear infrastructure prevents animals from movin.....»»

Political orientation—not party—predicts political tolerance: Study
In an age of high political polarization in the United States, the popular narrative often focuses on an "us versus them" battle between the two major political parties, each accusing the other of intolerance......»»
Scientists develop novel mode of linear hybridization chain reaction
Hybridization chain reaction refers to an enzyme-free nucleic acid polymerization reaction. A target molecule triggers cascade hybridization reactions by several thermodynamically stable DNA fuel strands, producing ultra-long DNA nanostructures with.....»»
Phobos surface striations tell a story of its rupturing interior
Phobos, the 22-km diameter innermost moon of Mars, is a groovy body. Unlike its little brother Deimos, Phobos has developed a striking pattern of parallel linear features running across its surface. These grooves are a distinctive global feature of P.....»»
