Because Grain Size analysis can be performed reliably in gray scale mode (where setting threshold parameters is simpler than color mode), the chosen camera should be capable of imaging in gray scale mode as opposed to color only. Also, choosing a camera that can achieve a fast refresh-rate in live mode will help when focusing or positioning the sample.

a reliable, accurate method of making grain size measurements. This lead to the establishment of several standard methods. Perhaps the most widely used method is the mean lineal intercept, or Heyn’s, technique. The mean lineal intercept length is the average length of a line segment that crosses a sufficiently large number of grains. It is proportional to the equivalent diameter of a
