Mollenstedt biprism and partial coherent electron beam interference
An expression for electron deflection angle caused by Mollenstedt biprism was deduced according to the similarity between electron optics and geometrical optics. A comparison between optical Fresnel and Mollenstedt biprism was given. The effects of partial coherence of electron beam on interference field were pointed out. The obtainable maximum number of interference fringes were discussed.
