\"HunterLabLa mesure pr\u00e9cise des couleurs des flocons d’avoine<\/strong>, avec calcul de la moyenne statistique \u00e0 l’aide de l’Appareil de mesure des couleurs Agera L2, s’av\u00e8re particuli\u00e8rement utile pour les flocons d’avoine, car ceux-ci font partie des \u00e9chantillons compos\u00e9s de particules diverses et pr\u00e9sentant une r\u00e9partition de couleur<\/strong> ou une texture de surface irr\u00e9guli\u00e8re<\/strong>. Dans tous les cas, les \u00e9chantillons doivent \u00eatre mesur\u00e9s au moins deux \u00e0 cinq fois, avec une rotation ou un nouveau remplissage entre les mesures, de sorte qu’une moyenne<\/strong> significative puisse \u00eatre calcul\u00e9e. L’\u00e9cart-type<\/strong> et la distance (dispersion) peuvent \u00eatre lus pour chaque mesure individuelle.<\/p>\n

Le tableau 1 pr\u00e9sente les r\u00e9sultats de cinq mesures distinctes r\u00e9alis\u00e9es \u00e0 l’aide de l’Agera L2 de HunterLab<\/strong>. Pour ce faire, des flocons d’avoine issus d’un m\u00eame lot ont \u00e9t\u00e9 vers\u00e9s dans une cuvette en verre de 6 cm de diam\u00e8tre et la couleur a \u00e9t\u00e9 mesur\u00e9e \u00e0 travers le fond de la cuvette<\/strong>. Entre chaque mesure, la cuvette a \u00e9t\u00e9 vid\u00e9e puis remplie \u00e0 nouveau \u00e0 partir du m\u00eame lot. La moyenne a ensuite \u00e9t\u00e9 calcul\u00e9e \u00e0 partir de ces cinq mesures. L’\u00e9tendue (dispersion) et l’\u00e9cart-type des valeurs permettent d’\u00e9valuer les variations des r\u00e9sultats de mesure pour ces \u00e9chantillons peu homog\u00e8nes. <\/p>\n

\"TableauxDans le tableau 2, cinq (5) mesures d’une valeur chacune ont d\u00e9j\u00e0 \u00e9t\u00e9 moyenn\u00e9es pendant la mesure, ce qui a permis de r\u00e9duire la dispersion. La couleur du lot est finalement d\u00e9termin\u00e9e avec une grande pr\u00e9cision gr\u00e2ce \u00e0 la moyenne des cinq r\u00e9sultats, comme le montrent les valeurs nettement plus faibles de l’\u00e9cart et de l’\u00e9cart-type.<\/p>\n

La mesure par le bas \u00e0 travers le fond de la cuvette<\/strong> est particuli\u00e8rement avantageuse pour les \u00e9chantillons \u00e0 petits grains ou les poudres, car elle permet d’obtenir une structure de surface plus uniforme<\/strong> que celle obtenue en regardant par le haut. De plus, l’Agera est \u00e9quip\u00e9e d’une cam\u00e9ra<\/strong> sp\u00e9cialement int\u00e9gr\u00e9e qui permet de capturer une image de l’\u00e9chantillon telle qu’elle est \u00ab vue \u00bb par le capteur. En outre, un histogramme RVB de l’enregistrement peut \u00e9galement \u00eatre affich\u00e9 simultan\u00e9ment. Cet enregistrement peut \u00eatre sauvegard\u00e9 avec les donn\u00e9es de mesure.<\/p>\n
