可扩展式自适应光学系统波前处理器的硬件设计

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.
