Cophasing multiple aperture telescopes with Linearized Analytic Phase Diversity (LAPD)
Sebastien Vievard, Aurelie Bonnefois, Frederic Cassaing +2
Focal plane wavefront sensing is an appealing technique to cophase multiple aperture telescopes. Phase diversity, operable with any aperture configuration or source extension, gene…
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…
PERSEE: Experimental results on the cophased nulling bench
Julien Lozi, Frédéric Cassaing, Jean-Michel Le Duigou +15
Nulling interferometry is still a promising method to characterize spectra of exoplanets. One of the main issues is to cophase at a nanometric level each arm despite satellite dist…
