Dielectric barrier discharges in helium is investigated by temporally and spatially resolved optical emission spectroscopy. Focus of our investigation was He I 447.15 nm line which can be used in electric field measurements. At maximum discharge current the spatial line intensity distribution and the electric field distribution are characteristic for the cathode fall region. Estimated electric field strength distribution is in agreement with theoretical calculation. Temporal evolution of He I 447.15 nm line during the breakdown is also studied.
