| Abstract: | In an adaptive optics system, the wavefront reconstruction and the control algorithm are calculated by the wavefront processor whose speed and time-delay limitthe control bandwidth of the system. A highspeed real-time warefront processor withfive TMS32OC5O chips and one TMS32OC31 chip was designed to fit the 838Hz Shack-Hartmann wavefront sensor. The parallel-process and pipe-line technologies were used,the maximum speed is 3OOMflops, and the time-delay of the wavefront processor is only0. 7ms. |
