Assuming I've understood this even half-way correctly...

It sounds like the accuracy of your triangulation will be limited by
the small size of the FR; and when you add in the hardware and
software path latency, I wonder if this will work accurately enough.
(I'm assuming the marker would be a few metres away from the FR, is
that right?)

I think that points in a similar direction to Al's comment, i.e.
moving some of the solution outside the FR, over USB.  That would
allow you to have more distance between the inputs, and so get more
