CANARY has been designed to demonstrate full tomographic LGS MOAO in a configuration as close as possible to that of the proposed EAGLE instrument for the E-ELT. A phased approach to the instrument development has been adopted to reduce the overall risk and developmental complexity with the initial Phase A system performing NGS MOAO only using three off-axis NGS WFS. The Phase B system will add four off- axis open-loop LGS WFSs to this system...
