Asgard/NOTT: water vapor and CO atmospheric dispersion compensation system

Romain Laugier, Denis Defrère, Michael Ireland +8

To leverage the angular resolution of interferometry at high contrast, one must employ specialized beam-combiners called interferometric nullers. Nullers discard part of the astrop…
