Talking Yup see the issue

"The results are repeatable to the 100 nm level
and may be used to identify bearing characteristics"

Thats 10 to power negative 7 (metres). That's achievable!
10 to power negative 9 is developing in "nano engineering"
As yet not in public domain.

Look up "micro" and "nano".
