Abstract

As a part of the adaptive optics (AO) upgrade at the Subaru Telescope, we started developing a non-linear curvature wavefront sensor (nlCWFS), which is a new visible WFS for the upgraded facility AO system of the Subaru Telescope. We have successfully installed the nlCWFS on the Subaru Telescope following our previous lab demonstrations. This talk presents the commissioning of the nlCWFS. We first present the installation process of the nlCWFS and closed-loop performance with an internal source. We also highlight the recent on-sky results with the nlCWFS. We conclude by comparing the AO performance before and after the AO upgrade and with future works for implementing the non-linear wavefront reconstruction algorithms.
