Kerr electro-optic field mapping measurements are presented in electron beam irradiated polymethylmethacrylate (PMMA) where the accumulated trapped charge results in large self-electric fields of the order of 1 to 2.5 MV/ cm. The resulting numerous light maximum and minimum recorded on photographic film and videotape allow accurate measurement of the time dependence of the electric field and space charge distributions.
