A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams ...

Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, ...

White light interferometry is increasingly being adopted for thin film measurement and high‑precision distance applications ...

A team of physicists has shown that pairs of helium atoms, chilled to near absolute zero and launched into each other, can behave as though each atom travels two separate paths at the same time. The ...

Interferometers are research instruments that are utilized in many disciplines of science and technology. Interferometers are so-called because they function by combining multiple sources of light to ...

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in multiple states at once.

Polytec's optical measurement equipment focuses on dynamic response measurements. MEMS devices typically have actively moving ...
