The x-ray interferometer is not a joke. In about 1974, Gerd Materlik built one
for his thesis and inserted it in front of my beamline at the DESY synchrotron.
The beam splitters and "mirrors" were all carved out of a single block of
perfect single crystal silicon. He inserted a wedge of plastic
Dear Bernhard,
your paper is actually not so much of a joke. Are you aware of K. Huemmer's
and E. Weckert's three-beam experiments? See e.g.

Bear in mind that position of the interferometer mirror or whatever
would have to be constant to within a fraction of an Angstrom- breathe
on the frame and it will warm ever so slightly- the expansion will
change the
phase of the reference beam by a few thousand wavelengths. A real

That's fascinating! Can such an interferometer actually be constructed for
an
X-ray beam line or is this still in the realm of the theoretical possible?
