Presence/absence?

It also might do a really good job at giving you proximity if you KNOW
what the substance will be, and therefore the reflectivity of it.  An
example might be paper rolling by in a printing press.

Incidentally, if you want I have a circuit which uses 1 opamp to do a
good photodiode receiver, send me e-mail off list and I'll get it to you.
