  The characteristic and distinctive features of the visibility amplitude of
interferometric observations for compact objects like stars in the immediate
vicinity of the central black hole in our Galaxy are considered. These features
are associated with the specifics of strong gravitational scattering of point
sources by black holes, wormholes, or black_white holes. The revealed features
will help to determine the most important topological characteristics of the
central object in our Galaxy: whether this object possesses the properties of
only a black hole or also has characteristics unique to wormholes or
black_white holes. These studies can be used to interpret the results of
optical, infrared, and radio interferometric observations.
