But there’s a problem. While it’s a simple matter to build mirrors and beam splitters for photons, it’s extremely difficult to do that for matter waves. As a result, matter-wave interferometers are ...

The field of levitated optomechanics has experienced significant advancements in manipulating the translational and rotational dynamics of optically levitated particles and exploring their sensing ...

A nodeless antiresonant fibre. (Courtesy: Gregory T Jasion, Optoelectronics Research Centre, University of Southampton) A new type of hollow-core optical fibre makes light-based gyroscopes up to 500 ...

(PhysOrg.com) -- When a spinning laser gyroscope is placed near a super-cooled rotating ring, the gyroscope accelerates a bit in the same direction as the ring, and scientists aren’t sure why. The ...

Gyroscope designs used in inertial navigation systems (INS) fall into three basic groups: the classic spinning-rotor mechanical gyro (still in use in specialized situations due to its superior ...

The first gyroscope was invented in 1852 by Leon Foucault (a traditional mechanical gyroscope of this general type is shown in Fig 1). Foucault thought that he could measure the rotation of the earth ...
