摘要:

机器人光纤定位器在生成大规模光谱测量中发挥着至关重要的作用。定位器组协调得越完整,其对应的摄谱仪在观测期间接收的信息就越多。研究了位置集的完全协调问题。我们首先定义了局部和全局完备性问题,并确定了它们之间的关系。然后,我们提出了一种新的人工势场,根据该人工势场,定位器及其相邻定位器的收敛性被协同考虑。我们还发现了一个完整的协调所需的条件。最后,我们解释了如何修改的定位器集的一些参数可能会解决其不完全协调的情况。我们使用模拟来验证我们的成就。

英文摘要:

Robotic fiber positioners play a vital role in the generation of massive spectroscopic surveys. The more complete a positioners set is coordinated, the more information its corresponding spectrograph receives during an observation. The complete coordination problem of positioners sets is studied in this paper. We first define the local and the global completeness problems and determine their relationship. We then propose a new artificial potential field according to which the convergences of a positioner and its neighboring positioners are cooperatively taken into account. We also discover the required condition for a complete coordination. We finally explain how the modifications of some of the parameters of a positioners set may resolve its incompleteness coordination scenarios. We verify our accomplishments using simulations.
