The Four-Quadrant Phase Mask Coronagraph. II. Simulations
In the rst article (Rouan et al. 2000) we have described the principle of a coronagraph utilizing a four-quadrant phase-mask and the results of numerical simulations obtained in the perfect case. In this second article, we have performed additional numerical simulations to assess in more detail the performances and limitations of this coronagraph under real conditions. The eeect of geometrical ...
متن کاملAstronomical near-neighbor detection with a four-quadrant phase mask (FQPM) coronagraph
Direct detection of planets around nearby stars requires the development of high-contrast imaging techniques, because of their very different respective fluxes. We thus investigated the innovative coronagraphic approach based on the use of a four-quadrant phase mask (FQPM). Simulations showed that, combined with high-level wavefront correction on an unobscured off-axis section of a large telesc...
متن کاملFour Quadrant Phase Mask: Analytical Calculation and Pupil Geometry
Of the many novel coronagraphic and nulling techniques that have been suggested to improve image contrast for exoplanet detection, one of the most promising is the Quadrant Phase Mask suggested by Rouan et al.. Analysis of this optical system has previously been performed by discrete Fourier transform methods, that result in systematic errors due to the implicit assumptions of the methods and m...
متن کاملAnnular Groove Phase Mask Coronagraph
We present a new phase mask coronagraph consisting in an optical vortex induced by a space-variant surface relief subwavelength grating. Phase mask coronagraphy is a recent technique aiming at accommodating both high dynamic and high angular resolution imaging of faint sources around bright objects such as exoplanets orbiting their parent stars or host galaxies of active galactic nuclei. Subwav...
متن کاملExtinction-controlled adaptive phase-mask coronagraph
Context. Phase-mask coronagraphy is advantageous in terms of inner working angle and discovery space. It is, however, still affected by drawbacks such as sensitivity to tip-tilt errors and chromatism. A nulling stellar coronagraph based on the adaptive phase-mask concept using polarization interferometry is presented in this paper. Aims. Our concept aims at dynamically and achromatically optimi...
