Recently, in the dark skies over the Magdalena Ridge Observatory Interferometer (MROI), an optical interferometer conducted an operational demonstration: capturing data on a satellite in ...

Researchers exploit quantum entanglement to measure the interference of light signals from two distant detectors, opening a path toward quantum-enhanced astronomy. In the researchers’ setup, two ...

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 ...

Accurately controlling film thickness and uniformity is extremely important for both throughput and performance in the automotive, aerospace, semiconductor, medical, and research industries. White ...

The relentless pursuit of higher precision in semiconductor lithography and atomic-scale manufacturing demands measurement systems capable of sub-nanometer accuracy, multi-axis capability, and robust ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...

A high-resolution imaging system captures distant objects by shining laser light on them and detecting the reflected light. Seeing the small picture. The remote-imaging system (left) shoots eight ...

Future space missions could use quantum technologies to help us understand the physical laws that govern the universe, explore the composition of other planets and their moons, gain insights into ...

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 ...
