An achromatic eight - octant phase - mask coronagraph using photonic crystal
For direct detection of faint exoplanets, high-contrast imagers would be indispensable for strongly suppressing central bright stars. In particular, extremely high contrast of 10−10 will be needed for detecting Earth-like planets. An eight-octant phase-mask (EOPM) coronagraph is one of promising concepts because of its high-contrast performance, small inner working angle, and simple optical con...
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...
متن کاملThe Achromatic Interfero Coronagraph
We report on the Achromatic Interfero Coronagraph, a focal imaging device which aims at rejecting the energy contribution of a point-like source set on-axis, so as to make detectable its angularly-close environment (applicable to stellar environment : circumstellar matter, faint companions, planetary systems, but also conceivably to Active Galatic Nucleii and multiple asteroids). With AIC, star...
متن کاملThe 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 ...
