Nonsense, that's simply radar. Use Greenfield's notation, c' = c+v.
If the light hits the mirror at c' then it reflects from the mirror at -c'.

Ooh! Science from Androcles!

Not Ritz's emission theory then. Majorana's experiments (Phil mag 35, 163
(1918), Phil Mag 37, 145 (1919)) support Ritz's emission theory over this
reflect at speed of c' relative to the mirror emission theory.

(Miller's Michelson-Morley with sunlight dis-supports both of
those versions, in favour of c relative to the mirror, a "new source"
emission theory.)

I don't see how that follows. Where is the moving mirror?
If there is a speed change of the source, it is the same in both arms.

More important is the fact that the beam passes through a glass plate, which
could easily cause the beams to emerge at god knows what speed.
