(PhysOrg.com) -- When a spinning laser gyroscope is placed near a super-cooled rotating ring, the gyroscope accelerates a bit in the same direction as the ring, and scientists aren’t sure why. 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 ...

Interferometric fiber optic gyroscopes (IFOGs) exploit the Sagnac effect to measure rotation with extreme precision. Light from a coherent source is split into counter-propagating beams within a coil ...

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 ...

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 ...
