Optical Point-Spread Function via Defocus Phase Retrieval in Scanning Electron Microscopy
Surya Kamal, Kevin Mogere Nyaburi, Richard K. Hailstone
The point-spread function of the probe-forming optics () is reported in an uncorrected (without multipole correctors) scanning electron microscope (SEM). In an SEM, i…
