Paper Abstract

In the DARWIN study, the European Space Agency has for several years investigated the possibilities for a mission, dedicated to direct detection of earth-like life on extra- solar planets. The detection technique is based on nulling interferometry, i.e. suppression of the on-axis star, such that only light from orbiting planet(s) remains. The concept of Generalized Angel's Cross (GAC) is introduced. A GAC is a nulling interferometer made up of four telescopes, all at equal distance from the interferometer's center and flown in one plane perpendicular to the common optical axis.
