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 ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

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 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 ...

A new imaging technology developed at the University of Connecticut promises to rewrite the rules of optical imaging, ...

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 ...

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 ...

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

The days of measuring for first downs manually isn't over yet, but the NFL is moving closer to that point. The league has been testing optical tracking as a way to replace the chain gang as the ...
