CA 2612947

The invention relates to recording of position-specific optical measurements of substances such as foodstuff, building materials, combustion products etc. The invention provides online, in-situ recording of wavelength absorption spectra in substances, performed without removing a sample from the substance. In inhomogeneous products, the position correlated to each spectrum allows for extraction of both average values for larger regions as well as specific values characteristic for smaller individual portions. In a preferred embodiment, a probe with two elongate arms has light guiding and light collecting means for recording infrared absorption spectra of portions between them, as well as means for determining an insertion distance into the product. The invention may be applied to as different substances as diary products (cheese, cream, milk), fruit, berries, seeds, meat, vegetable and animal fat, animal feed, water, wine, beer, lemonades, oils, rubber and plastic materials, gypsum and plaster, cement and concrete mixes, paints, glues etc.

L~invention concerne l~enregistrement de mesures optiques spécifiques à la position, ces mesures portant sur des substances comme les aliments, les matériaux de constructions, les produits de combustion, etc. L~invention permet un enregistrement in situ, en ligne d~une pluralité de spectres d~absorption de longueur d~onde dans des substances, enregistrement réalisé sans prélever d~échantillon dans la substance. Dans les produits non homogènes, la position corrélée à chaque spectre permet l~extraction à la fois de valeurs moyennes pour des régions plus grandes et de valeurs spécifiques caractéristiques pour des portions individuelles plus petites. Dans un mode de réalisation préféré, une sonde avec deux bras allongés possède un moyen guide de lumière et collecteur de lumière pour enregistrer des spectres d~absorption infrarouge de portions entre ceux-ci, de même qu~un moyen pour déterminer une distance d~insertion dans le produit. L~invention peut s~appliquer à des substances aussi différentes que les produits laitiers (fromage, crème, lait), les fruits, les baies, les graines, la viande, la graisse végétale et animale, le fourrage, l~eau, le vin, la bière, les limonades, les huiles, le caoutchouc et les matériaux plastiques, le gypse et le plâtre, le ciment et les mélanges de béton, les peintures, les colles, etc.
