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 ...
Closing the loop on a V8 piezo linear motor with a laser interferometer: resolution down to 0.15 nanometers is achievable.
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 ...
X-ray astronomy is a somewhat neglected corner of the more general field of astronomy. The biggest names in telescopes, like ...
Controlled magnetic gradients The atom chip used to create the magnet-based interferometer in the experiment. (Courtesy: Yair Margalit) An Israeli-led collaboration has used atom-chip technology to ...
The MICHELSON-MORLEY EXPERIMENT was performed in the basement of a WESTERN RESERVE UNIV. dormitory in July 1887 by ALBERT A. MICHELSON of the Case School of Applied Science and EDWARD W. MORLEY of ...
NASA has selected a new mission to study how the Sun generates and releases giant space weather storms – known as solar particle storms – into planetary space. Not only will such information improve ...
