摘要

为满足大型地基高分辨率成像望远镜对自适应光学系统波前处理的需求

需设计千单元的自适应波前处理系统。为此提出了一种可扩展式的自适应光学系统波前处理器。系统由波前处理主板和波前处理子板组成

每块波前处理主板可扩展10块波前处理子板。整个系统可以完成2 000帧/s的实时波前图像的采集、子孔径斜率的计算、波前拟合和1 200路的控制促动量输出的任务。详细给出了整个系统的硬件设计方案、实施过程和实验结果。

Abstract

For the need of lager ground-based high resolution EO imaging telescope adaptive optics wave-front processing

thousands of units AO wave-front processing system is required to design. In this paper

an extendible adaptive optics wave-front processor has been presented. This system uses wave-front processing host board and wave-front processing sub board

and can realize expansion according to the scale of adaptive system. Each wave-front processing sub board can promote the output of 120 roads

with the maximum expansion capacity of 10

the system can reach 2 000 frames/s sampling and processing frequency and promote the momentum of the output of 1 200 roads. This article gives a detailed design

implementation and test results.
