Abstract

Abstract

Adaptive optics has wide applications in astronomical observation realm because of its high capacity in improving the spatial resolution. Compared with night astronomical adaptive technology for star observation, the observation and correction for low contrast extended target at the solar surface is always a difficulty in adaptive optics. In reference to low contrast extended character of adoptive optics in solar observation, FFT correlation coefficients algorithm is utilized and a large array adaptive optoelectronic system is designed. The system, with DSP+FPGA architecture, consists of low-order correlation tracking part and high-order wave-front processing part. The experimental result shows that the system well satisfies pre-design requirements and thus demonstrates good flexibility, versatility and scalability of the scheme.
