Abstract
dc.description.abstract
We propose and demonstrate a low-cost magnetomechanical fiber micro-positioner for optical coupling, with a
square-millimeter working range and a resolution of a few
microns per pixel. We demonstrate the functionality of the
positioner as a beam pattern imaging system for a 14” Dobsonian
telescope as it is compact enough to be mounted instead of a
small-telescopes eye-piece. The aim is to use this positioner to
couple and stabilize a telescope beam to a single-mode fiber. We
make a first approach to a reference model controller showing
an increase of the average coupled power under perturbations
from 54% to 85%.
