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 ...

Optical computing has emerged as a powerful approach for high-speed and energy-efficient information processing. Diffractive ...

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 ...

Measuring super smooth surfaces generally necessitates the use of optical metrology tools, but it is important to note that optical solutions are not all the same. The choice of metrology solution for ...

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 ...

(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 ...

Computational fluorescence microscopy (CFM) requires accurate point spread function (PSF) characterization for high-quality ...

Complex fluids, such as polymer melts and concentrated suspensions, are foundational materials for industrial products, ...

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 ...
