The double-exposure electron holographic technique has been put into practical use for the first time. By this method an accurate recording of the distribution of electric and magnetic fields can be directly obtained by the electron microscope without resorting to sophisticated optical manipulation of the holograms. Problems concerning the operative definition of the contour maps are discussed. Experimental results are presented.
