Toward fast calibration of global drift in scanning electron microscopes with respect to time and magnification
It is a well-known fact that the scanning electron microscopic image acquisition is mainly affected by nonlinearities and instabilities of the column and probe-specimen interaction; in turn producing a shift in the image points with respect to many parameters, time, in particular . Even though this drift is comparatively less in modern SEMs, it is still an important factor to consider in most o...
متن کاملAutomatic estimation and correction of anisotropic magnification distortion in electron microscopes.
We demonstrate a significant anisotropic magnification distortion, found on an FEI Titan Krios microscope and affecting magnifications commonly used for data acquisition on a Gatan K2 Summit detector. We describe a program (mag_distortion_estimate) to automatically estimate anisotropic magnification distortion from a set of images of a standard gold shadowed diffraction grating. We also describ...

متن کاملMicroscopes for neurophysiology
Bioso£t's neurophysiology simulation program, Neurosim, has now been released as a Windows package. The new version has been completely rewritten to take advantage of the Windows interface. The user first selects the experimental and neurophysiological parameters desired for a particular simulation, and then runs an experiment. The computer generates a graphical display similar to that of an os...
متن کاملEmbryos, microscopes, and society.
Embryos have different meanings for different people and in different contexts. Seen under the microscope, the biological embryo starts out as one cell and then becomes a bunch of cells. Gradually these divide and differentiate to make up the embryo, which in humans becomes a fetus at eight weeks, and then eventually a baby. At least, that happens in those cases that carry through normally and ...
