Abstract

Method for acquisition of at least one hologram of a sample by off-axis holography using a transmission electron microscope, the microscope comprising an electron beam source, at least one objective lens, a sample holder, at electron biprism and means of displacing the electron beam in precession mode upstream from the sample holder and a compensator of the precession downstream from the sample holder, said method comprising the activation of means of displacing the electron beam in precession mode and the compensator and acquisition of a hologram of said sample in precession mode.
