Electron tomography can provide three dimensional (3D) visualization of nanoscale objects in a transmission electron microscope (TEM) from a tilt series of projected images. The accuracy of the 3D reconstruction depends on quality of input parameters, including accurate alignment in real space and accuracy of tilt and azimuth angle measurements. Here we present an electron diffraction-based in-...
