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 ...

Italian scientists dip deep for laser experiments to measure Earth’s rotational effects at greatest ever sensitivity. GINGERino ring laser gyroscope at the underground labs of INFN in Gran Sasso, ...

"When the two light beams meet up, they greet each other like long-separated friends and continue on as if nothing had separated them. In other words, if we were to measure the properties of 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 ...

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 ...

Accurately sensing rotation is important to a variety of technologies, from today's smartphones to navigational instruments that help keep submarines, planes, and satellites on course. In a paper ...
