Optical design of a multi-resolution, single shot spectrograph
Francois Henault, Florence Laurent
Multi-object or integral field spectrographs are recognized techniques for achieving simultaneous spectroscopic observations of different or extended sky objects with a high multip…
Quantum physics and the beam splitter mystery
Francois Henault
Optical lossless beam splitters are frequently encountered in fundamental physics experiments regarding the nature of light, including "which-way" determination of light particles,…
Field of View and contrast limitations of stellar interferometers. A quick review
Francois Henault
Field of View (FoV) and contrast limitations of stellar interferometers have been the scope of numerous publications for more than thirty years. Recently, this topic regained some…
Current results of the PERSEE testbench: the cophasing control and the polychromatic null rate
Julien Lozi, Frederic Cassaing, Jean-Michel Le Duigou +11
Stabilizing a nulling interferometer at a nanometric level is the key issue to obtain deep null depths. The PERSEE breadboard has been designed to study and optimize the operation…
Can violations of Bell's inequalities be considere as the final proof of quantum physics ?
Francois Henault
Nowadays, it is commonly admitted that the experimental violation of Bell's inequalities that was successfully demonstrated in the last decades by many experimenters, are indeed th…
Computing extinction maps of star nulling interferometers
Francois Henault
Herein is discussed the performance of spaceborne nulling interferometers searching for extra-solar planets, in terms of their extinction maps projected on-sky. In particular, it i…
