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 non-isoplanatism 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<sup>2.</sup><sub>″</sub> (s)], suggest that the atmosphere induced field-of-view limitation is about 2 arcsec at optical wavelengths and about 50 arcsec at infrared wavelengths.
