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 ...

Optical waveguides form the backbone of modern photonic systems, guiding light with minimal dispersion and facilitating functions from high-speed data transmission to precision sensing. Characterizing ...

The invention of optical fibers has revolutionized not only telecommunications but also sensing technology. Optical fiber sensors can measure strain, temperature, pressure, and many other physical ...

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) ...

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 ...

Transmitter testing methods prior to TDECQ. Why TDECQ has overtaken TDP in PAM4 transmitter testing. Steps in the TDECQ measurement process. Using sampling oscilloscopes with built-in TDECQ.

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 ...

Semiconductor devices are becoming thinner and more complex, making thin deposited films even harder to measure and control. With 3nm node devices in production and 2nm nodes ramping toward ...
