System Overview of Subaru AO188 AO188 module Subaru AO188 is an 188 element curvature sensor adaptive optics system that are operated in both natural guide star (NGS) and laser guide star (LGS) modes.

Performance of Subaru AO188 Performance of AO is characterized by a Strehl ratio (a peak intensity normalized by that of PSF without any turbulence) and FWHM of the PSF. These depend on a the AO guide ...
