Can someone please explain how a Sagnac ring laser gyro or fiber-optic gyro seems to violate SRT, since the second postulate of SRT holds that the speed of light does not vary in vacuum regardless of the position or motion of any observer (in this case, receivers)? And how is it even possible to reconcile Sagnac's formula with the Lorentz Transform - which, the way I think I understand it, by design takes the non-relative aspect of the Sagnac formula which gave it its form for practical use - and plugs it into SRT to make it relative? Does this question make any sense? Thanks.
