Abstract: Electric microfields inside or outside charged latex particles(0.31μm) and fine structure of magnetic domains in a permalloy film,are investigated by digital reconstruction from electron holograms.Resolution is improved by means of noise-filtering and phase-difference-amplification.Some new results are reported.
