      abstract     = {The technique of double exposure electron holography, which
                      is based on the superposition of two off-axis electron
                      holograms, was originally introduced before the availability
                      of digital image processing to allow differences between
                      electron-optical phases encoded in two electron holograms to
                      be visualised directly without the need for holographic
                      reconstruction. Here, we review the original method and show
                      how it can now be extended to permit quantitative studies of
                      phase shifts that oscillate in time. We begin with a
                      description of the theory of off-axis electron hologram
                      formation for a time-dependent electron wave that results
                      from the excitation of a specimen using an external stimulus
                      with a square, sinusoidal, triangular or other temporal
                      dependence. We refer to the more general method as
                      continuous exposure electron holography, present preliminary
                      experimental measurements and discuss how the technique can
                      be used to image electrostatic potentials and magnetic
                      fields during high frequency switching experiments.},
