Abstract

We present the ASSI (Active Stabilization in Stellar Interferometry) interferometric experiment presently under realisation for use with the 2-Telescope interferometer of CERGA (I2T). A detailed presentation of the instrument project was given in ref.¹, and progress on the realization were indicated in ref.². We review the principles and expected performances of our system and, in particular, the real time, flux optimized, fringe tracking system that we developped using synchronous detection technique on cooled silicium diodes in the near Infrared.
