Title
(EN) METHOD FOR IDENTIFYING INTERNAL PARAMETER OF AN EGG
(FR) PROCÉDÉ D'IDENTIFICATION D'UN PARAMÈTRE INTERNE D'UN ŒUF
Abstract
(EN)
An active thermography method for identifying at least one internal or subsurface parameter of at least one egg is disclosed. The method comprises thermally exciting at least a surface of the at least one egg with a means for excitation such that the egg is provided in a non-equilibrium thermal condition for a non-equilibrium period having duration ttransient; obtaining a thermogram at a plurality of time intervals (N) of the at least one egg in during the non-equilibrium period, resulting in N thermograms; determining at least one parameter in dependence upon the N thermograms; and identifying the at least one internal or subsurface quality parameter of the at least one egg based on the at least one parameter.
(FR)
L'invention concerne un procédé de thermographie active permettant d'identifier au moins un paramètre interne ou de sous-surface d'au moins un œuf. Le procédé comprend l'excitation thermique d'au moins une surface dudit œuf à l'aide d'un moyen d'excitation de telle sorte que l'œuf soit soumis à une condition thermique de non-équilibre pendant une période de non-équilibre présentant une durée ttransient ; l'obtention d'un thermogramme à une pluralité d'intervalles temporels (N) dudit œuf pendant la période de non-équilibre, permettant l’obtention de N thermogrammes ; la détermination d'au moins un paramètre en fonction des N thermogrammes ; et l'identification desdits paramètres de qualité interne ou de sous-surface dudit œuf en fonction desdits paramètres.
