Abstract
In the lecture the innovation of the 2-line ratio method for electric field determination in dielectric barrier discharges was presented. The already published method of Ivkovic et al. was enhanced to enable direct highly-resolved 2D measurement of electric field (E/N) development in helium coplanar DBD. The key innovation stands in the usage of optical interference filters mounted on the ICCD camera, together with precise temporal alignment using the binocular filter system for simultaneous 2D resolved capture of discharge emission of HeI 667.8 nm and HeI 728.1 nm lines.
