In research that could broadly benefit science, medicine and engineering, a new kind of ultrasensitive optical sensing instrument has been developed by a doctoral student at The University of Alabama ...

We present the first controlled-environment measurements of the optical path-length change response of telecommunication submarine cables to active seismic and acoustic waves. We perform the ...

White light interferometry is a well established technique with diverse precision applications, however, the conventional interferometers such as Michelson, Mach-Zehnder or Linnik are large in size, ...

Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...

In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped ...

The patented QTec® laser technology reinvents laser vibration measurements by eliminating the root cause of noise, delivering superior optical sensitivity and enabling high-fidelity measurements on ...

One of the biggest challenges for nanoscale fabrication is how to measure devices on such a minute scale. As the semiconductor industry demands ever smaller devices, the need for reliable, robust ...
