摘要：

In this paper, the results from a computer simulation comparison between curvature AO-systems using APDs and a special-purpose curvature-CCD, the MIT/LL CCID-35, are presented. The simulated AO-system is the MACAO 60-element curvature system(1), which is being developed by ESO for the Very Large Telescope (VLT) and VLT Interferometer (VLTI). The results indicate a difference in performance of 5% Strehl in K-band for a 15(th) magnitude guide star, 2% Strehl for a 16(th) magnitude star, and less than 0.6% Strehl for all other magnitude guide stars.
