I would think that running the device with the axis tilted 45 deg. off center to the left, and then to the 45 deg. off center to the right, would allow for normalizing out the effects of mechanical shifting or warping. This is a simple problem to resolve. I am planning on building a small, very small version of the device with a laser diode, etc... in a much smaller form factor on a single substrate. This should minimize any mechanical issues. Using a CCD pickup and computer to analyze the motion in much finer detail should also help. Anyone spare some parts? Small high grade mirrors etc.. to set this up?

I have no doubt the fringes will shift by pushing against this particular beam splitter. What one needs is a "sag-o-meter". Wait... doesn't this apparatus perform this function? :-) harry
