You can use a photodetector: See http://www.oz.net/~coilgun/levitation/photodetector.htm He uses a 15V supply, but that seems arbitrary. I'd use 10V. You can also eliminate the voltage follower op-amp, accepting that the current draw on the Vdd line will make the response non-linear. Still, once calibrated, it should be consistent.
