Abstract
La présente invention offre une pluralité déchantillons, chacun deux comprenant des particules dune dimension prédéterminée, à lintérieur de limites étroites prédéterminées, dispersées dans un support selon une concentration de particules prédéterminée. La dimension de particule prédéterminée et la concentration de particules prédéterminée sont identiques pour chaque échantillon. Toutefois, de manière avantageuse, chaque échantillon présente un rapport prédéterminé différent dune valeur dune propriété optique des particules à une valeur de la même propriété optique du support. Linvention propose également un procédé pour sélectionner un échantillon cible à partir de la pluralité déchantillons pour évaluer la précision de la mesure ou la sensibilité de la détection dun analyseur de particules optiques alors que le rapport prédéterminé sapproche de 1.
