摘要

为了保证大空域多目标光纤光谱望远镜(LAMOST)系统能够准确运行，有必要对LAMOST焦板上光纤的位置进行测量。需要将前照提取的光斑位置与单元的实际位置进行匹配。在位置匹配的研究过程中，在原有匹配模式的基础上，提出了一种更适合于正面照射方法的新模式(最小匹配方法)。该方法有效地解决了前照法匹配中存在的光点过多、位置随机、计算复杂等问题。

Research on position matching of LAMOST fiber units

In order to ensure that the Large Sky Area Multi-Object Fiber Spectroscopy Telescope(LAMOST)system can run accurately,it is necessary to measure the position of optical fibers on the focal plate of LAMOST.It is needed to match on the position of light spot extracted by front illuminate with the actual positions of units.During the study of position matching,a new pattern(the minimum matching method)based on the old one and more appropriate to front illuminate method is presented.With the new method,problems found in matching of front illuminate method,such as excessive amounts of light spots,random location,complicated calculations,are solved effectively.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
