| Research Abstract |
We demonstrate quantitative electron holographic tomography using a latex sphere as a simple example. For performing potential profiling in the presence of a missing wedge, the region of interest should ideally be aligned perpendicular to the rotational axis. Although a simple object is used, we believe that the observations made in this study will lead to further developments in electron holographic tomography. In particular, we make the quantitative interpretation mainly deals with of artifacts caused by incomplete angular information, i.e., a "missing wedge.", showing an important implication of the solution.
