Abstract

Adaptive optics (AO) works in many cases in the partial correction regime, i.e. with a Strehl ratio lower than 0.8. In this regime, seeing variations induce some variations in the correction (see Tessier 95), as shown on Fig. 1 which plots the Strehl ratio for continuous frames taken with the Come-On Plus instrument (see Beuzit et al. 94 for a description of this instrument).
