Application of a damped Locally Optimized Combination of Images method to the spectral characterization of faint companions using an Integral Field Spectrograph
Laurent Pueyo, Justin R. Crepp, Gautam Vasisht +14
High-contrast imaging instruments are now being equipped with integral field spectrographs (IFS) to facilitate the detection and characterization of faint substellar companions. Al…
Optimal Dark Hole Generation via Two Deformable Mirrors with Stroke Minimization
Laurent Pueyo, Jason Kay, N. Jeremy Kasdin +4
The past decade has seen a significant growth in research targeted at space based observatories for imaging exo-solar planets. The challenge is in designing an imaging system for h…
Design of PIAA coronagraphs over square apertures
Laurent Pueyo, N. Jeremy Kasdin, Alexis Carlotti +1
The purpose of this paper is to present the results of a theoretical study pertaining to the feasibility of PIAA units using Deformable Mirrors. We begin by reviewing the general d…
Propagation of Aberrations through Phase Induced Amplitude Apodization coronagraph
Laurent Pueyo, N. Jeremy Kasdin, Stuart Shaklan
The specification of polishing requirements for the optics in coronagraphs dedicated to exo-planet detection requires careful and accurate optical modelling. Numerical representati…
Improved High Contrast Imaging with On-Axis Telescopes using a Multi-Stage Vortex Coronagraph
Dimitri Mawet, Eugene Serabyn, J. Kent Wallace +1
The vortex coronagraph is one of the most promising coronagraphs for high contrast imaging because of its simplicity, small inner working angle, high throughput, and clear off-axis…
