Shouldn’t we consider the special relativity ? because the speed of light is always “c”. if the moving particle was any other particle except photon, this explanation make sense.
In a FOG you compare phase differences of the input wavelength. In a RLG you compare optical laser modes. Laser modes can be much narrower than a single wavelength and depend of the quality factor of your laser. A laser can easily have a quality factor of several thousands. Making the optical modes several times finer than a single wavelength
Really easy to understand! Thank you , this is the best video that explain the principles of a optical gyroscope
Very nicely explained. The Sagnac effect should be better known by its actual name since it it in common use in our everyday lives. Thank you.

Why does no one explain why RLG is so much more sensitive than a fiber interferometer alone?

Please explain, how it understands the true North?
It would come from calibration, the equipment doesn’t “understand” cardinal bearings
