摘要：

A description is made of a grating optical system for extracting phase distribution from electron holograms, that has an extremely high stability and can eliminate system aberrations. Phase measurement is achieved with phase-shifting interferometry by stepping the grating laterally. The system is used to extract the phase distribution of a magnesium oxide crystal from its electron hologram.
