Weibel 3 - GW3

In this simplest form, sterology is the science where information about a three dimensional object is obtained from only a two-dimensional section of that structure.

Measurements are usually made with these graticules in the following manner:

1. An adequate representation of sections of a specimen is obtained.
2. The graticule is superimposed upon the specimen (or micrograph/projected image of the section).
3. Finally, the interaction between the superimposed graticule and the test sections are recorded.

An overall introduction is given by: L.B. Brianrty. "Stereology: Methods for Quantitative Light and Electron Microscopy."
