Hi Jerry, glad to see you back!
I believe the problem is in the test equipment/setup.  If it were on the
surface of the mirror, the orientation of the 'ying yang' would rotate with
the surface of the mirror.  Perhaps too much separation of the grating and
the light source.

best of luck,
Scott Donaldson
