Abstract
We report preliminary results on fringe pattern acquisition and stabilization as performed on a Mach- Zehnder set up representative of Stellar Interferometry needs. The system algorithm is based on "white light" fringe tracking controlled from a reference interferometer synchronous detection (central fringe locked interferometry). This servo-system drives a simple two-stages delay line for real time compensation of the optical path delays either due to atmospheric or instrumental errors. Contrasts (nonoptimized) of 70 % on the stabilized fringe pattern were measured, strongly encouraging to pursue the development of the technique.
