Abstract
Atmospheric fluctuations cause a jitter in the fringe position of ground-based stellar interferometers. To efficiently use the few photons available, an active fringe tracking system is necessary to stabilize the fringe position. This paper briefly describes the different methods of fringe tracking being implemented at the CHARA array, as well as the fringe tracking systems themselves.
