Résumé: he UVic AO Lab in collaboration with HIA and the Subaru telescope is currently designing Raven, a multi-object adaptive optics (MOAO) demonstrator that will be coupled to the Subaru Infrared Camera and Spectrograph (IRCS). Its main goal will be to demonstrate MOAO feasibility on the sky while allowing astronomers to beneficiate from the increased observing efficiency associated with such systems.
INO is responsible for the Raven calibration unit design and
fabrication. This sub-system consists in a telescope simulator that
will allow aligning Raven’s components during its integration, testing its AO performances in the laboratory and at the telescope, and calibrating the AO system by building the interaction matrix and
measuring the non-common path aberrations (NCPA). This subsystem
is described in this poster.
