Hi there,

The problem which requires to be solved its a small distance measurement
at high speed (about 15cm/second) in a high EM radiation environement
(near a few KW generated from 300KHz inductors). The medium distance to be
measured is about 2mm, between a a metal surface which have inflexions
(it's not a plane surface) and a moving tool. The metal surface is painted,
dirty and gruffly, where the paint+dirt have a variable thickness.
The generators can't be shutted off while the measurement is performed.
I will be glad to hear any possible ideea from specialists (or just
thinkers) from these lists.

thank you in advance,

Vasile
