My East-West light speed anisotropy experiment and the null result.
This animation is a vital component of this post.
It fills in the blanks.

................
The following video clip was extracted from my east-west light speed
anisotropy experiment which was based on Fizeau's ether drag experiment
in 1859.

The outcome from that experiment was a null result. There was no
evidence of an east-west light speed anisotropy.
But I had very little confidence in that outcome. Did I really
understand these interference patterns?
---
The setup used for the Michelson-Morley experiment in 1880 can be used
to demonstrate that the interference pattern I was using was valid for
the task.
The light paths can be analysed idividually and simply by unfolding
the two arms at the beam return mirrors and taking a laser beam source
and half silvered mirror with them.
---
There will of course be no interference patterns generated by the
beams from two different sources.
---
Before I go any further, the integrity of the half silvered mirror
needs to be tested.
---
Take note of the double image when the laser beam is reflected off
the glass face.

This half silvered mirror is the point of focus for the two beams of
the unfolded MMX device. One leg is pointing east, while the other
point
