ABSTRACT:
A process for batch interferential granulometry applicable particularly to poly-dispersed biological particles. The process is characterized in that the positioning of the angular measurement regions is selected according to the criteria of representativity of the signals obtained with respect to the given granulometry sought, particularly for their alternative components, and in that the processing of the signals comprises successively a harmonic Fourier analysis of their alternative components, and the use of the results of this analysis in a computation leading to the parameters sought, namely, the numbers, mean dimensions, and granulometric distribution of the analyzed particles.
