Scientific paper

The Active Stabilization in Stellar Interferometry (ASSI) experiment conducted with the CERGA two-telescope interferometer is presently discussed with a view to the features and performance of its near-IR, cooled-silicon diode synchronous detection-based real-time and flux-optimized fringe-tracking system. Attention is given to ASSI's optical path delay correction, which is a function essential to the achievement of a cophased array suitable for optical imaging. Photometric rates as high as 1.2 million/sec have been achieved.
