Control interface concepts for CHARA 6-telescope fringe tracking with CHAMP+MIRC
Cophasing six telescopes from the CHARA array, the CHARA-Michigan
Phasetracker (CHAMP) and Michigan Infrared Combiner (MIRC) are pushing the
frontiers of infrared long-baseline interferometric imaging in key scientific
areas such as star- and planet-formation. Here we review our concepts and
recent improvements on the CHAMP and MIRC control interfaces, which establish
the communication to the real-time data recording & fringe tracking code,
provide essential performance diagnostics, and assist the observer in the
alignment and flux optimization procedure. For fringe detection and tracking
with MIRC, we have developed a novel matrix approach, which provides
predictions for the fringe positions based on cross-fringe information.Comment: 6 pages, 4 figures, published in SPIE conference proceedings
