That sounds good. So, the light comes out of the telescope and you put
it through the wheel with a notch in it, and split the light two
different ways and measure not the interference but the actual time it
takes it to go some distance. Then do the same thing with it going two
other directions. The distances and maybe times would be compared to
light whose source is at rest wrt the telescope. The stationary laser
could shine through a different notch.

The major problem may be getting funding, since emission theories are
probably considered so thoroughly discredited that it isn't interesting
to test them. Maybe it could be done as a control for some other
experiment. Like, you have some other experiment that requires you to do
all that setup, and then you measure the speeds as a control, and if
they are different you correct for the difference so the primary
experiment can proceed correctly.

Poor old Crank,....stilll doesn't get it....

There is NO actual frequency to worry about in sagnac. Wavelength is intrinsic
to each photon. 'Frequency' is a inferred quantity defined as the number of
waves passing a point in the inertial frame per second.
Photons possess spatial 'waves', as in inertial's 'rope analogy'.

The path lengths of the rays are different, therefore the number of turns of
the rope are different in each ray and they meet out of phase.

This is terribly simple really. I don't know why you are having so much
difficulty understanding it.

A photon is a LONG particle....like your rope....

Let me try to explain in even mire basic terms. (I will try to imagine I am
talking to a Chimp)

In the inertial frame, the emission and detection points OF A PARTICULAR PHOTON
ELEMENT are stationary and are separated by the distance vt. (even your SR
agrees)
The emission and detection points OF the NEXT PARTICULAR PHOTON ELEMENT are
also stationary.....BUT THEY ARE DISPLACED FROM THE PREVIOUS ONES.

Both points are progressively 'moving' because different elememts are being
progressivlely emitted but they are always separated by 2piR+vt and 2piR-vt for
the two rays.
