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 ...

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 ...

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, ...
