A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...

WE have succeeded in applying multiple-beam interference methods to the study of the surface movements of oscillating quartz crystals, and the striking results obtained indicate that this has opened ...

This is a preview. Log in through your library . Abstract Applying holographic interferometry, local instantaneous air fuel ratio has been measured in the evaporating fuel spray injected into the ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

If you want to get the greatest benefit from a beam of light - whether to detect a distant planet or remedy an aberration in the human eye - you need to be able to measure its beam front information.

Closing the loop on a V8 piezo linear motor with a laser interferometer: resolution down to 0.15 nanometers is achievable. Here's how it works: https://www.pi-usa.us ...

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 ...

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 video shows the workings of optical coherence tomography (OCT). OCT makes it possible to inspect layers under the skin surface in a non-invasive manner and helps develop three-dimensional (3D) ...

Warming up: illustration of the interferometer. (Courtesy: APS / Alan Stonebreaker) An atom interferometer that does not have to be cooled to cryognenic temperatures has been created by physicists in ...
