What is the definition of RLG?
Stands for ring laser gyroscope. A RLG is an optical gyroscope that uses narrowband light waveforms travelling a path, created using mirrors, to measure rotation based on the Sagnac effect.

Any rotation of the device will cause the light beams to reach the optical receiver at different times due to the Sagnac effect, which can be extrapolated into a measurement of rotation
