Scientific paper

In astronomical interferometer the interference signal is often detected on the pupil plane. To achieve good signal strength it is necessary to keep the wavefront distortions caused by the optics and the atmosphere small. This paper indicates that it often suffices to make the wavefront distortions in the pupils equal rather than zero to achieve good signal strength. A way to achieve this is by using a differential adaptive optics approach is proposed.
