摘　　要：针对LAMOST光纤定位系统中球焦面上 4 0 0 0根光纤端部位置需要进行快速、精确定位的特点 ,根据定位目标多 (4 0 0 0个 )、定位速度快 (1～ 2min)的要求 ,提出定位系统总体控制方案、分析 4 0 0 0个光纤定位单元的扫描控制方法。Parallel controllable optical fiber positioning system can be applied for 4000 optical fibers positioning on the convex focal plate of LAMOST (Large Sky Area Multi-Object Fiber Spectroscopy Telescope) rapidly and precisely. According to the requirement of many positioning objects (4000 optical fibers) and fast positioning speed,in this paper is advanced a general control method for the positioning system ,and analyzed the control method of scanning 4000 optical fibers positioning unit.
