Abstract
A rotary stage microdensitometer was interfaced to an Apple II personal computer for the purpose of making rapid rms granularity measurements. An experimentally determined relationship was found between standard deviation in voltage and rms granularity. By using this relationship the device proved accurate to within 7 percent of the known values of rms granularity on a conventional microdensitometer for the same samples with 95 percent confidence.
