Yes, that's the obvious reply, but evidently it didn't satisfy the two 
physicists quoted above from the essay you recommended.

Can you bounce the light off a mirror, or send it through a lens, before 
running it through the two slits, and still get fringes? I would assume 
that you can't, because that *would* be a "measurement".
