Imaging and nulling properties of sparse-aperture Fizeau interferometers
F. Henault
In this communication are presented rigorous and approximate analytical expressions of the Point Spread Function (PSF) and Field of View (FoV) achievable by multi-aperture Fizeau i…
Simple alternative model of the dual nature of light and its Gedanken experiment
F. Henault
In this paper is presented a simple alternative model of the dual nature of light, based on the deliberate inversion of the original statement from P. A. M. Dirac: "Each photon int…
Metrology calibration and very high accuracy centroiding with the NEAT testbed
A. Crouzier, F. Malbet, O. Preis +19
NEAT is an astrometric mission proposed to ESA with the objectives of detecting Earth-like exoplanets in the habitable zone of nearby solar-type stars. NEAT requires the capability…
Cheapest nuller in the world: Crossed beamsplitter cubes
F. Henault, A. Spang
In this communication is described a new type of Achromatic phase shifter (APS) suitable for both nulling interferometry and coronagraphy, based on a couple of crossed beamsplitter…
SPIRou: the near-infrared spectropolarimeter/high-precision velocimeter for the Canada-France-Hawaii telescope
Étienne Artigau, Driss Kouach, Jean-François Donati +30
SPIRou is a near-IR échelle spectropolarimeter and high-precision velocimeter under construction as a next-generation instrument for the Canada-France-Hawaii-Telescope. It is desig…
