Fourth-order coronagraph
WebOct 15, 2006 · We describe a high-contrast imaging technique capable of directly measuring light from a terrestrial planet by using a vortex mask of topological charge m = 5. We demonstrate that this technique is relatively insensitive to low-order aberrations and compare its performance to that of a band-limited Lyot coronagraph.

Results from Roman's Coronagraph Instrument will demonstrate the technology that will enable future missions to observe and characterize rocky planets in the habitable zone of their star – the range of orbital distances where liquid water could potentially exist on a planet’s ...
WebThis multi-layered technology, the Coronagraph Instrument, might more rightly be called “starglasses”: a system of masks, prisms, detectors and even self-flexing mirrors built to block out the glare from distant stars — and reveal the planets in orbit around them. WebA fourth-order “pupil-swapping coronagraph” is particularly attractive for direct imaging of extrasolar terrestrial planets: it achieves 100% throughput at 1.4l/d on a square pupil …
WebAbstract: We propose a coronagraphic system with fourth-order null for off-axis segmented telescopes, which is sufficiently insensitive to the telescope pointing errors and finite angular diameter of the host star to enable high-contrast imaging of potentially habitable planets. The inner working angle of the coronagraphic system is close to $1\lambda/D$, and … WebOct 30, 2012 · Graph ordered pairs in the four quadrants of the coordinate plane.
