Minimum differences in height detectable in electron stereomicroscopy

Abstract

Measurements were carried out to test the validity of Heidenreich and Matheson's relation for the vertical resolution attainable in electron stereomicroscopy. Relative elevations much smaller than this relation would allow were readily detected. Considerations are advanced which indicate that if certain considerations are satisfied, the minimum detectable difference in height may approach and perhaps better the lateral resolution of the microscope.
