An optical system comprising a c-cut uniaxial crystal positioned between two axicons and illuminated by a Gaussian or a Laguerre–Gauss mode was used to demonstrate the generation of various vector ...

Light manipulation at the nanoscale is essential both for fundamental science and modern technology. The quest to shorter lengthscales, however, requires the use of light wavelengths beyond the ...

Light fields, as a form of electromagnetic waves, are characterized by fundamental parameters including intensity, phase, and polarization. Precise imaging of these three parameters is crucial for ...

A team of researchers has built an intelligent sensor—the size of about 1/1000 of the cross-section of a human hair—that can simultaneously detect the intensity, polarization and wavelength of light, ...

A structured light refers to a light field which is "customized" in both space and time, characterized by its unique distribution of amplitude, phase, and polarization state in both space and time.

Under the impact of big data and artificial intelligence, optical detection techniques based on single physical quantities can no longer meet the needs of acquiring multi-dimensional information in ...

In 1927, the term "picture element," later abbreviated to "pixel," appeared for the first time in the American technology magazine Wireless World. Today, pixels are everywhere: in computer screens and ...

How do polarization technologies work? Advances in imaging technologies. Imaging sensors have undergone many advances in the past two decades. At the heart of it all was enabling better pictures that ...

A research group led by Assistant Professor Takafumi Tomita and Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed a new microscopy ...

Can you use a single atom to capture an image? Single atoms are probably not replacing smartphone cameras soon, but an atom ...
