The nature of quantum particles has long puzzled scientists. While single-particle interference suggests that a photon can behave like a spread-out wave, a whole photon is only ever detected in one ...

Measuring high aspect ratio and composite micro-trenches without damage is critical for advanced microfabrication, yet conventional coherence scanning interferometry often suffers from a low signal-to ...

Earth's atmosphere is an impediment to astronomical observations. Not only is cloudy weather a problem, but temperature fluctuations in the atmosphere mean that ground-based telescopes require ...

In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped ...

Discover a compact solution for full-field optical vibration measurement with VibroScan QTec. This video demonstrates how its patented multi-path interferometry delivers high data quality and how the ...

Optical Surfaces Ltd has received an order from Armstrong Optical, a leading UK supplier of optical metrology instruments, to supply high specification transmission and reference flats for a custom ...

The bandgap defines how insulators absorb light and conduct electricity. XUV high-harmonic interferometry now lets researchers track its femtosecond dynamics. (Nanowerk News) The bandgap, i.e. the ...

In the Journal of Astronomical Telescopes, Instruments, and Systems, researchers report a comprehensive modernization of ...
