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 ...

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 ...

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 ...

There are two kinds of gyroscopes in widespread use for navigation and control: optical ones, which are extremely sensitive but also expensive, and microelectromechanical (MEMS) ones, which are ...
