Precision
The measurement sensitivity depends on how rapidly the laser is tuned and how well systematic errors are controlled. Currently precisions of a few nm over a 6m path are possible in evacuated interferometers. In a system built for the ATLAS experiment a target of 1 micrometre precision over distances of 1 m is expected to be easily achieved.

Famous quotes containing the word precision:
“One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical precision that twice two is seven.”
—Anton Pavlovich Chekhov (1860–1904)
“Women on trains
have a life
that is exactly livable
the precision of days flashing past”
—Audre Lorde (1934–1992)
“Concision in style, precision in thought, decision in life.”
—Victor Hugo (1802–1885)
