The invention discloses a piezoelectric tilting mirror high-voltage driver with the function of compensating the frequency characteristic of an object, comprising a communication interface (1), a digital compensator (2), a digital-to-analog converter (3), and a high-voltage amplifier (4). It is: the communication interface (1) receives the digital control signal sent by the wave front processor, after performing digital compensation in the digital compensator (2), it enters the digital-to-analog converter (3) and converts it into an analog control signal, and then passes through the high-voltage amplifier (4) Amplify the high-voltage power signal to drive the piezoelectric tilting mirror. The digital compensator can real-time compensate the amplitude response at the mechanical resonance frequency of the piezoelectric tilting mirror, which is the driving object of the high-voltage driver, so as to solve the influence of the mechanical resonance peak of the piezoelectric tilting mirror on the adaptive optical servo system. The invention is suitable for high-speed and high-voltage driving of piezoelectric tilting mirrors in the field of adaptive optical systems.
