WebThis example demonstrates how to use FFTs to measure distances between atomic planes in high resolution transmission electron microscopy (TEM) images. It requires ImageJ 1.33i or later. Figure 1. High resolution TEM … WebTransmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through …
