Ultrashort laser pulses—that are shorter than a millionth of a millionth of a second—have transformed fundamental science, ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.220024 considers a precise measurement technology of optical coherent structure of random lights. Optical manipulation and ...

A research team at VTT MIKES has set a new record in optical-clock absolute frequency measurements using a strontium single-ion clock with exceptionally low uncertainty and high uptime.

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving ...

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 ...

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) ...

A laser Doppler vibrometer’s (LDV) real-time capability enables measurement times roughly six orders of magnitude smaller compared to any method that is based on strobe techniques or provides a ...

(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 ...

A collaboration between TU Wien (Vienna), and the universities of Glasgow and the Grenoble, have posed fundamental questions about the nature of precise measurement using light: what is the absolute ...

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 ...
