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 ...

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 ...

Some days really are longer than others. And now scientists know by precisely how much. Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth ...

Laser gyroscopes represent a pivotal technology in measuring Earth’s rotation with unmatched precision, utilising the Sagnac effect to detect minuscule angular variations. These instruments, often ...

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 ...

After 30 years of painstaking development, researchers in Germany and New Zealand have unveiled a laser gyroscope that can track fluctuations in Earth’s rotation in near real time and accurate to ...

The modern smartphone is only possible because of sensors. Their svelte form factor conceals accelerometers, magnetometers, temperature sensors, a GPS unit, and gyroscopes. They all consume volume and ...
