Wow, must be pretty magic because i can repeatibly put a bit of paper between the emitter and the detector and remove the signal without changing any other bit of the set up.......    :-DD
Dave:
Color me impressed. :-+
Would you mind posting a schematic of your circuit?

I'll grab some scope traces if i get a chance this weekend!  :-+
StillTrying:
I hope I'm wrong, but I think your 10ns-wide 3ns-delayed received pulses are just noise from the switching-on edge of the emitter, many of my captures show it.
