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 ...

Fiber optic gyroscopes (FOGs) utilise the Sagnac effect to measure rotation, forming the core technology behind many modern inertial navigation and rotation-sensing applications. These sensors offer a ...

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 ...

Traditionally, gyroscopes were mechanical devicesthat measured the angular rate of rotation. Onecommon use of gyroscopes has been in navigationsystems to provide heading estimation.Installing these ...
