摘要
介绍了LAMOST光纤定位中间试验系统的研制及测试情况.试验系统主要包括如下几个部分:控制主机,单元控制器,驱动电路,19个光纤定位单元,面阵CCD摄像头,图像采集卡,以及自行开发的控制程序.进行的定位精度测试表明系统各单元的定位精度总体满足要求(不超过40μm).
A construction of LAMOST fiber positioning medium-term system （including 19 units） and its tests are briefly introduced. This system includes a main control computer, a unit controller, a set of drive circuits, 19 execution units on the focal plane, a CCD camera, a frame grabber, and control programs. Tests on the system indicate that positioning precision of the 19 units is no more than 40μm on the whole.
