Appendix 1A Stereomicroscopy
Appendix 1A StereomicroscopyFrom B. L. Gabriel, SEM: A User's Manual for Materials Science, American Society for Metals, Metals Park, Ohio, 1985.Although SEM images appear three-dimensional, their very format reduces them to two-dimensional representations. Their multidimensional appearance is due to high depth of focus, but perspective distortions introduced by the geometry of the beam/specimen/detector invalidate spatial measurements (both height and lateral dimensions). Our subjective impressions are based on the direction of illumination, which cannot be adequately described in a single micrograph produced by a complex geometry. These problems are aggravated when rough-surfaced specimen…
