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 visible light by ...

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a new way to measure distances at the nanoscale—one nanometer being one billionth of a meter—using light.

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) ...

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 ...

Precision manufacturing relies on accurate and precise dimensional metrology for process monitoring and control. Simply put, it is impossible to sustain a manufacturing process that is both accurate ...

Ellipsometry is a non-destructive, optical measurement technique that characterizes the optical properties of thin films. It is highly sensitive to changes in the thickness and refractive index of the ...

Sneezes, rain clouds, and ink jet printers: They all produce or contain liquid droplets so tiny it would take several billion of them to fill a liter bottle. Measuring the volume, motion and contents ...

The NFL’s use of the decidedly low-tech 10-yard chain to measure first downs could be replaced by high-tech optical tracking. The league today revealed that a system to measure first downs ...

(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 ...
