how to measure the relative movement of two body
(OP)
I am trying to figure out what is the best way to measure the relative movement of two body.
Here is the confguration:
1. the normal distance is about 20mm.
2. the relative movement can be +/- 10mm.
3. those two body are made of steel and their shape are irregular.
4. the temperature is about 1000F.
5. The movement of each body could be in 3 dimensions.
Any brillant ideas? What technology / sensor to use?

What accuracy do you need? Without that information it is kinda pointless to speculate too much.

The accuracy I need is less than 0.5mm.

1) What is used to move the 2 bodies, or are they moving by themselves?
2) What is the effect of 1000°F on steel expansion? And, does this have to be taken into account?

We can consider the steady state of thermal expansion.
Thanks!
