Abstract :
Reports the experimental generation of a linear optical path modulation of 20 lambda range with an accuracy of lambda /200 ( lambda =633 nm) using a servo control system driving an optical fibre stretcher. The error signal is provided by mixing interferometric signals with an electronic oscillator.
