The bandgap defines how insulators absorb light and conduct electricity. XUV high-harmonic interferometry now lets ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...

Space-momentum domain interferometer is a key technique in modern precision measurements, and has been widely for applications that require superb spatial resolution in engineering metrology and ...

Interferometers are widely used in various high spatial resolution imaging techniques to extend the diffraction limit. However, the conventional interferometric methods only work when the photons have ...

This image compares data from two Iceye Synthetic Aperture Radar images. Changes in the vertical height of the surface appear black. Areas without changes are depicted in white. Credit: Iceye SAN ...

Grating-coupled interferometry (GCI) is a surface based, a label-free optical sensing technique used for real-time binding kinetic measurements. 1 Typically, GCI is used to detect binding events ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

Microlenses have many applications, such as coupling light into fiber optics, enhancing light source uniformity in microdisplays, and focusing light onto imaging sensors in mobile phone cameras.

Flow cytometry is an incredibly useful analytical tool that has revolutionized the way in which single-cell and particle characterization is performed. Despite its effectiveness, flow cytometry ...

The concept of measuring surface roughness originated nearly a century ago as a means to prevent uncertainty and disputes between manufacturers and buyers. Now, it has become a common identifier used ...

Toward the development of a “quantum compass” for navigation when GPS signal unavailable. Sandia scientists prepare a rubidium cold-atom cell for an interferometry experiment. Scientists are ...
