Abstract

This paper compares the closed-loop, adaptive-optics-system performance obtained with a Shack-Hartmann wavefront sensor (WFS) to that of a fixed-pyramid WFS, assuming a point-source beacon. To quantify performance, the analysis uses wave-optics simulations and calculates the peak Strehl in weak to moderately deep turbulence conditions. Initial results show that the Shack-Hartmann WFS outperforms the fixed-pyramid WFS.
