Abstract
A tandem interferometer system linked with a 100 mu m core diameter mu ltimode fibre has been investigated and a signal-processing scheme int roduced to suppress the noise in the system, simulated by a reproducib le vibration of the fibre. The results show a short-term repeatability (to three standard deviations) of better than 15 nm displacement with the use of an appropriate curve-fitting signal-processing scheme, und er conditions where the fibre is subjected to a known noise signal by being constantly subjected to vibration.
