用场发射电子显微镜拍摄了晶体微粒的电子象全息图。在光学重构阶段中，使用光学透镜作为补偿器来校正电子透镜的球面像差。从精确聚焦的电子显微镜图像中的粒子分离的晶格图像形成在球形校正图像中的粒子内部，并且给出关于金粒子的晶格的正确信息。
Electron image holograms of a crystalline fine particle are made with a field emission electron microscope. The spherical aberration of the electron lens is corrected in the optical reconstruction stage, using an optical lens as a compensator. Lattice images separated from the particle in the exactly focused electron microscopic image are formed inside the particle in the spherically corrected image and give correct information on the crystal lattice of the gold particle.
