Nuller
Sign in to saveA 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.

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.
The VLT interferometer’s visiting instrument Asgard's submodule NOTT (Nulling Observations of exoplaneTs and dusT) contains such a nuller to combine four telescope signals to perform nulling interferometry.
