Abstract

To distribute more fiber positioning nodes on the LAMOST focal plate, two steps are proposed to miniaturize the fiber positioning node in this paper. The first step is to miniaturize the mechanical device of the fiber positioning node. The second step is to redesign the entire wireless driving board using smaller and performance-higher devices. As a result, the size of the new miniaturized fiber positioning node has to be reduced by above 40% and the dense of fiber positioning nodes on focal plate increases by 20% at least.
