Integration of the atmospheric fluctuations in a dual-field optical interferometer: the short exposure regime

, 2003
Spatial phase-referencing in dual-field optical interferometry is reconsidered. Our analysis is based on the 2-sample variance of the differential phase between target and reference star.
