Interferometry is a measurement technique that exploits the superposition of coherent waves, typically electromagnetic or matter waves, to extract precise information from the resulting interference ...

We suspect there are three kinds of people in the world. People who have access to a Michelson Interferometer and are glad, those who don’t have one and don’t know what one is, and a very small number ...

A state-of-the-art experiment at the US Department of Energy’s (DoE) Fermi National Accelerator Laboratory is one step closer to collecting experimental data. Fermilab has announced that it has ...

Go visit a sacred ancient site, if possible one featuring a high density of megalithic architecture, and when you get back tell me, hand on heart, you didn’t feel something. Modern archaeology, for ...

Make an inexpensive laser interferometer. An optical interferometer splits a beam of light into two beams that travel at right angles, then recombines them. The resulting interference pattern reveals ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Interferometry is a technique that combines light waves to produce interference patterns, which can be analyzed to measure distances, shapes, and surface features with extreme precision. 1 Thanks to ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...
