Primary performance data for passive fiber-optic devices is provided by spectral measurement of optical insertion loss (IL) and polarization-dependent loss (PDL). Often used to characterize optical ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

Complex fluids, such as polymer melts and concentrated suspensions, are foundational materials for industrial products, including high-strength plastics and optical components. The final performance ...

Irregularities on a surface determine how rough it is. Surface roughness can be evaluated by visual appearances and tactile sensation and can be measured using a numerical scale. A surface condition ...

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 ...

Portable 3D optical inspection with 4Di InSpec transforms surface metrology, enhancing defect detection and quality assurance ...

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 processes that ensure reliability and safety of ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...
