Seeing effects removal in a Michelson stellar interferometer.
Abstract
There is no unique definition of the fringe contrast in a random structure such as the image given by a Michelson stellar interferometer. A definition is given which leads to a contrast value independent of the seeing conditions provided the wave-front perturbations on the two apertures are uncorrelated. Moreover, if simultaneous observations through a single aperture are available, the seeing effects can be completely removed.
