Chalcogenide fiber bundle for 3D spectroscopy

Abstract A fiber bundle is fabricated for use in three-dimensional spectroscopy. The bundle has 100 fibers with chalcogenide glass cores (As 2 S 3 ) whose shape of the cutting surface is square. The fibers are arrayed 10 × 10, and 1 × 100 on the input and output side, respectively, whereby two-dimensional images are reformatted into a linear array. The output beams from fibers are dispersed by a grating and their spectra are detected simultaneously on a two-dimensional photo-detector. Preliminary results obtained by our fiber bundle are presented here.
