SEM
SEM stands for Scanning Electron Microscope. It is a type of electron microscope that produces high-resolution images of a sample by scanning it with a focused beam of electrons. The electrons interact with the atoms in the sample, producing signals that can be detected and used to create an image. SEM is widely used in the field of space and astronautical engineering to analyze the surface morphology and composition of materials used in spacecraft and other space-related applications.
