Abstract:

With the advantages of small size, big push power, high frequency response and high resolution, piezoelectric ceramic actuators have been widely used in the fields of precise manufacture, optical instrument, vibration control，and etc. In order to improve the control accuracy and stability of the piezoelectric ceramic fast steering mirror，a driving power is designed on account of high voltage operational amplifier PA96 with the demand of piezoelectric ceramic actuator to its driving power. The basic principle of the power circuit is introduced，and the outside circuit of the amplifier is steadily designed. Finally indicated by the test of experiments，the linearity of the power is greater than 99%, the static ripple voltage is less than 10mV and the dynamic performance is stable, so the power can reach the control requirement of fast steering mirror in the system of adaptive optics.

Key words: atmospheric optics, fast steering mirror, piezoelectric ceramic, high voltage operational amplifier, driving power
