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)
“We are often struck by the force and precision of style to which hard-working men, unpracticed in writing, easily attain when required to make the effort. As if plainness and vigor and sincerity, the ornaments of style, were better learned on the farm and in the workshop than in the schools. The sentences written by such rude hands are nervous and tough, like hardened thongs, the sinews of the deer, or the roots of the pine.”
—Henry David Thoreau (1817–1862)
“How should the world be luckier if this house,
Where passion and precision have been one
Time out of mind, became too ruinous
To breed the lidless eye that loves the sun?”
—William Butler Yeats (1865–1939)
