What is the Sagnac effect?
The Sagnac effect is
used in optical gyroscopes by sending two beams of light in opposite directions in a fibre optic coil or mirror directed path
. As the device rotates, the beam traveling against the direction of rotation experiences a slightly shorter path delay than the other beam.

Did the Sagnac effect disprove Einstein?
In 1913 Georges Sagnac [1], after performing his famous optical test, claimed that the result disproved Einstein's special relativity
. In the original experiment performed by Sagnac, light trajectory was a quadrangle.

What is the Sagnac effect in ring laser gyroscope?
It operates on the principle of the Sagnac effect which
shifts the nulls of the internal standing wave pattern in response to angular rotation
. Interference between the counter-propagating beams, observed externally, results in motion of the standing wave pattern, and thus indicates rotation.

What is the Sagnac effect fog?
Based on the Sagnac effect, FOGs are
passive systems that use light to calculate motion
. Rotations movements are measured by sending identical laser beams, in opposite directions, through a long fiber-optic coil.
