全息术是Gabor在1948年提出的[1].当时的想法是利用光学方法补偿电子透镜的球差以提高电子显微镜的分辨本领.五十年代中期,Mollenstedt等[2]利用电子双棱镜获得了衬度良好的电子干涉图,在实验技术上使电子全息术前进了一步.不久有人利用这种方法测定了晶体内部平均势,取得了一 Holography was proposed by Gabor in 1948.1 The idea of ​​the time was to use optical methods to compensate for the spherical aberration of the electron lens to improve the resolving power of the electron microscope. In the mid-1950s, Mollenstedt et al. [2] Good contrast of the electronic interference pattern, in experimental technology to make electronic holography a step forward. Someone soon used this method to determine the average internal crystal potential, obtained a
