Abstract
An inline electron holograph method for observing a specimen with a transmission electron microscope having an electron gun, a collimating lens system, two spaced objective lenses, a biprism, and an imaging means comprises the steps of: with the first objective lens forming a virtual image of a portion of the specimen; with the second objective lens focussing the virtual image at an intermediate image plane to form an intermediate image; and projecting the intermediate image onto the imaging means.
