Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...

(Nanowerk News) The Korea Research Institute of Standards and Science (KRISS) has developed a novel quantum sensor technology that allows the measurement of perturbations in the infrared region with ...

A European collaboration involving clock experts from the National Physical Laboratory (NPL), the Physikalisch-Technische Bundesanstalt (PTB) and the Istituto Nazionale di Ricerca Metrologica (INRIM) ...

(Nanowerk News) Devices that use light to see objects, such as microscopes, have a fundamental limitation based on the laws of physics, which is their resolving power. The smallest distance that ...

Simple optics display the part upside down and backwards on the glass screen. Corrected optics display the part right side up and backwards. Fully corrected optics yield an image identical to the part ...

For the first time, researchers have used ultra-thin layers of 2D structures known as metasurfaces to create holograms that can measure the polarization of light. The new metasurface holograms could ...

Some of the most revealing signals about human health are carried in fluids that are almost impossible to measure. Tears, ...

They may look unconventional but the photosensitive fibre structures being developed at MIT promise a new way to measure the amplitude and phase of an optical signal. Rob van den Berg talks to the ...
