Coronagraphy vs. Nulling
Subaru Telescope, 650 N.A'ohoku Pl., Hilo, HI 96720, USA
Nulling cancels out the light of a source by destructive interference between several beams, while coronagraphy is a much larger family of high dynamical range imaging techniques designed for single pupil telescopes. In this paper, nulling techniques and three different classes of coronagraphs are compared using criteria relevant to the detection of Earth-sized planets around nearby stars.
