Abstract

The field-of-view limitations to actively controlled long-baseline interferometry are investigated. Without resorting to any specific atmospheric model, it is shown that the deleterious effects of nonisoplanatism do not grow with further baseline separation (higher spatial frequency sampled). Numerical calculations, which assume an atmospheric model, plus recently acquired data on the vertical profile of turbulence $[C_n^2(s)]$, suggest that the atmosphere induced field-of-view limitation is about 2 arcsec at optical wavelengths and about 50 arcsec at infrared wavelengths.
