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 ...

Entomologists and mechanical engineers ordinarily have little to do with one another. The first study bugs; the second design machinery. But last week the Sperry Gyroscope Co., designers of highbrow ...
