Through focus series of images are collected from MgO nano-cube crystals in the transmission electron microscope (TEM). The experimental data is used to solve the transport of intensity equation (TIE) to retrieve phase maps, which portray the morphology of the cubes and are quantified by the mean inner potential V(0). Particular attention is given to the practical difficulties associated with TIE phase retrieval of non-conducting polyhedron particles.
通过聚焦系列图像，在透射电子显微镜（TEM）中从氧化镁纳米立方体晶体收集图像。实验数据用于求解强度传输方程（TIE）以检索相位图，该相位图描绘了立方体的形态，并通过平均内势V(0)进行量化。特别关注与非导电多面体颗粒的TIE相位检索相关的实际困难。
