But you know all this, it's just a smokescreen to
hide the fact that you now know that ballistic light
cannot explain the phase shift measured by the
photodiode in an iFOG because it is fused to the
light source.

It certainly can, ...

Go ahead then, show the derivation and you will win
the argument.

I already did. You have such a pathetically short attention span,
being an absolute idiot, that you can't read or understand plain English
or mathematics.

All your posts assumed the detector was
not on the turntable. This is typical and
from just four days ago and you said "I see
now what the problem is, you both think the
detector is moving." so you certainly hadn't
posted a valid analysis before that.

No indication of what is turning. That's MMX, not Sagnac.
MMX, no shift.


Now assuming that the source, mirrors and screen
are all on the turntable, should there be a beat
frequency on the screen?

Nope.
....
I see now what the problem is, you both think the detector
is moving. Just think of it as the light strobing on and off.
....
No but the photodetector on the end of a fibre ring
gyro is, and it is "on the turntable". That's where
this conversation started.

I don't know where you get that idea from. The photodetector
that is on the turntable is MMX, not Sagnac, and no fringe shift
is observed.
Grandpa stands beside a carousel, the two kids climb aboard,
start beside him, and walk around it in opposite directions.
They cross on the opposite side and meet again with a small
offset from grandpa, caused by the rotation of the carousel.
It doesn't matter whether they walk in 4 straight lines along chords
or a curve around the perimeter.

Henri insists Grandpa rides the carousel, and I am NOT
getting on it. I rather suspect he got that idea from listening
to you, judging from your insistence above.
He hasn't a hope in hell of programming a Sagnac model
with Grandpa riding along. The kids meet where they started
on the carousel, they do not meet at Grandpa.

We both knew the detector is moving. As you
said, "The kids meet where they started on
the carousel, ..." but Grandpa is riding on
it too, so they reach him at the same time.
Ritz predicts no time difference in the
Sagnac configuration. You haven't posted
any derivation since then in sci.astro that
says anything different and I agree with
everything above, Ritz predicts a null
result and is consequently falsified. That's
also what Henri's program shows.
