Adaptive Optics is an all-round subject with science and engineering included. It studies the theory, system, technology and project of automatic wavefront-correction. It has the excellent performance beyond the conventional optical system. And it has a wide application foreground in military affairs and popular area. Because of the complex structure and bulky volumes of adaptive optics instruments, it cannot be used in astronomical observations for astronomy lovers. Simplification and miniaturization of adaptive optics system will be the inevitable trend of its development.This paper proposed a simple and practicable adaptive optics system.In the scheme, it used a piezoelectric ceramic to adjust the angle of the incident light to revise atmospheric turbulences’disturbance for astronomical observation. This article used the aluminum plating film plane reflector to reflect the incident light, of which the reflectivity of it was at least98%.It would greatly reduced the light path loss in the process of reflection. According to this scheme, this paper adopted the ATmega328MCU to control the circuit using a serial port communication, to realize the control of circuit on LT3469chip, and even then to realize the regulation of the expansion amount of piezoelectric ceramic. Finally, the control program of MCU was redacted to realize the established function using the Arduino.In the end, the material object would be used to the test of astronomical observation experiment.In brief, the proof of experimental results shows that:this program designing of the adaptive optics instrument is feasible.According the pictures which are taken with adaptive optics instrument, we can see it can effectively correct distortions of light caused by atmospheric turbulence. In this paper, the simplify and miniaturization of the adaptive optics instruments have practical significance, this paper is a further study of adaptive optics commercialization of the foundation.
