Abstract

This paper discusses the requirements posed on the ESO Very Large Telescope (VLT) Interferometer by the applications that require a field-of-view larger than the Airy disk of the individual telescopes. The most essential requirement for such wide field-of-view use of interferometric arrays is the maintenance of the pupil configuration, which applies to all the details of this configuration. Not meeting this requirement leads to path-length differences among the rays of each of the telescopes composing the array. An error budget for the optical design parameters of the VLT Interferometer is derived.
