Abstract
An experimental study of electron holography was carried out with a newly developed field emission electron microscope. Off-axis holograms were formed with a Möllenstedt-type biprism, both in Fresnel holography and image holography. The resolution of reconstructed images was higher in image holography. The obtained image hologram of an evaporated gold particle was shown to contain the Bragg-reflected waves from its {111} planes. The holograms were optically reconstructed and lattice images under arbitrary focusing conditions were observed by adjusting the focus of the optical system. The maximum line resolution in reconstructed images was 0.12 nm, which is the half spacing of gold {111} planes.
