A nuller is an optical instrument, e.g., a beam combiner for nulling interferometry, used to block or cancel out a strong source so that fainter signals near that source can be observed. This is typically useful to detect off-axis exoplanet or exozodiacal dust by interferometrically nulling out the on-axis parent star.
Ein Nulling-Interferometer ist ein astronomisches Instrument zur Beobachtung schwacher Quellen, die sehr nahe bei hellen Quellen stehen.
