This paper reports on the results of experimental studies concerning the dynamical characteristics of a segmented phase-front correctors. We obtain values for the resonant frequencies when correcting for tilt and zero-order phase distortions. We study the characteristics of piezoelectric actuators based on the PKR-6 ceramic. We show that such actuators can be used to create adaptive optical systems with maximum test-signal frequencies as high as 60 kHz.
