Abstract

Les concentrations centésimales des constituants d'un échantillon de grains céréaliers ou d'autres produits agricoles dans un courant en circulation, sont déterminées pendant la récolte ou le traitement, au moyen d'un analyseur de l'infrarouge proche à courte longueur d'onde. L'analyseur irradie l'échantillon, mesure dans ce dernier la réflectance diffuse de longueurs d'onde séparées, et sépare spatialement la réflectance diffuse sous forme de réponse à des longueurs d'onde séparées. Ainsi, il est possible de détecter simultanément des intensités des longueurs d'onde séparées en parallèle à partir de la même partie de produit en cours d'analyse. Les constituants centésimaux de la substance peuvent être comparés ensuite à des constituants centésimaux pour la détermination des constituants du produit échantillon. L'analyseur de longueur d'onde selon l'invention peut ensuite être fixé au combiné agricole, de façon à pouvoir effectuer des mesures en temps réel sur le terrain.
