Accurate measurements of surface currents are crucial for coastal monitoring, rip current detection, and predicting the path ...

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 ...

Researchers have revealed more details about omnidirectional photoluminescence (ODPL) spectroscopy - a method for probing semiconducting crystals with light to detect defects and impurities. Tohoku ...

An innovative arrangement employing diverse electronic and optical principles and components leads to precision frequency ...

Ellipsometry is a total optical measurement technique. This method is employed to measure how the polarization of light changes when passing through a medium. The polarized light shows distortion ...

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 ...

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 several testing applications, non-contact measuring extensometers provide significant benefits over traditional, contact-type extensometers. One of their main features is in the name itself, as ...

Structural health monitoring (SHM) and condition monitoring are crucial for ensuring reliability and safety of engineering systems across aerospace, civil engineering, and industry. These systems are ...

(a) A scheme of temperature variable ODPL spectroscopy. The spectra of ODPL and SPL as well as r (ODPL intensity divided by SPL intensity) measured at (b) T = 300 K and (c) T = 12 K. (Image: Kazunobu ...
