Abstract
A scanner based on the principle of the classic microdensitometer was assembled for the purpose of rapid granularity determination. A rotary stage was used to allow the generation of a root-mean-square (rms) voltage signal proportional to rms Transmittance in the sample. A mathematical relation was then developed to calculate granularity. The scanner was calibrated and was proved capable of 10 percent accuracy with 95 percent confidence.
