Using wavefront reconfiguration and corrector is one of the effective approaches in improving the beam quality control of the high energy laser system. A general architecture of embedded wavefront process and control system, as well as the theoretic analysis of the reconfiguring and controlling algorithm, is given in this paper to achieve the measurement, reconfiguration and correction of the wavefront aberrance. Then, designs of high-speed wavefront process and driver control modules are discussed in detail. Based on the principle of full digital design, the mass data processing and command parameter generating can be accomplished on the hardware platform of digital circuit. By using the method of embedded adaptive control, the system can work in the unattended operation mode to control the beam quality of the high energy laser system.
