If the device I cited looks odd I would first study the mechanisms behind a fiber optic gyroscrope

I think i have a pretty good grasp on the rlg and interferometery in general. That said, the device still looks a little odd to me. Are the arrows showing the fiberoptic cable moving or is that just the direction of the light?

those light beams take different paths around the circle in opposite directions, they then recombine.

Just like a standard rlg.

They have it moving linearly with the same velocity as the fiber optic cable it is measureing.

So they are moving the cable? Wild, if so.

So I think it is the parallelogram experiment that actually rules out the detector motion

Again, i may be confused about what you are saying. Unless i am very much misunderstanding the diagram - the device will ONLY show interference pattern when the device is moving (and air is irrelevant). Right?
