A two dimensional scanning setup for precise addressing of fibers in a fiber bundle

A fiber optical scanning set-up is presented, which acts as a fiber addresser between an optical measurement system and a flexible waveguide bundle. A light beam is positioned and coupled into the optical fibers using a two-dimensional scanning mirror setup. The fiber positions are detected and sorted using software algorithms. After calibration, the fibers are read out individually at high rates in order to generate the measurement data. Multiplexing of an Optical Coherence Tomography (OCT) system through a singlemode linear fiber array consisting of 100 fibers with a core diameter of 5 µm is demonstrated.
