Paper Abstract

This paper investigates and compares wavefront sensing options for a proposed natural guide star adaptive optics upgrade for the Keck telescope. The methods of curvature sensing and slope sensing with a Hartmann sensor are compared. A curvature sensor model is developed that includes nonlinear, diffraction, and noise effects. The analytical model is validated in simulation using the Keck optical prescription parameters. A comprehensive treatment of estimation/reconstruction is presented and used for the Hartmann sensor/curvature sensor comparisons.
