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 ...

A lot of what I write is about measurement, not because I'm in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...

This article outlines how to measure, control, and stabilize the relative distance of two interferometer paths to sub-wavelength precision over numerous wavelengths, using the Zurich Instruments MFLI ...

The AIMS Interferometer represents over 20 years leading edge development resulting in easy to use, robust products, which have been specifically optimised for each measurement application. All ...

An illustration of the Berkeley group’s lattice interferometer, where the standing wave of a laser beam in a cavity suspends each atom in a spatially separated quantum superposition state, in the ...

Using an atom interferometer, scientists have tested one of the foundations of Einstein's general theory of relativity: that time slows down in a gravitational field. Their experiment proves that ...
