title: Photogrammetric calibration of electron microscopes.
abstract: Attention is drawn to sound mensural calibration of the electron microscope system. A general understanding of the inherent distorsions is imperative. By using the collinearity condition and a photogrammetric self-calibration technique, one obtains the patterns of scale, radial, tangential and spiral distorsions. These are discussed and fundamental concepts involving such calibrations are presented. Some actual data are presented for illustration purposes.
