Abstract[English]
The invention provides a method and associated device for determining a condition of the internal structure of hair. A hair sample is exposed to light or heat and a signal is recorded from part of the light or heat that has interacted with the hair sample. The signal is compared with a first calibration model to determine the condition of the internal structure of hair. The calibration model is obtained by determining the condition of the internal structure of calibration hair samples using a method that measures bulk properties of constituents of hair. Part of light or heat that has interacted with each calibration hair sample is also recorded a correlation is established between the recorded signals and the determined condition of the internal structure of the plurality of calibration hair samples.[French]
L'invention concerne un procédé et un dispositif associé servant à déterminer l'état de la structure interne de cheveux. Un échantillon de cheveux est exposé à de la lumière ou à de la chaleur et un signal est enregistré à partir d'une partie de la lumière ou de la chaleur qui a interagi avec l'échantillon de cheveux. Le signal est comparé à un premier modèle de référence pour déterminer l'état de la structure interne des cheveux. Le modèle de référence est obtenu par détermination de l'état de la structure interne d'échantillons de cheveux de référence à l'aide d'un procédé qui mesure des propriétés volumiques de constituants des cheveux. La partie de la lumière ou de la chaleur qui a interagi avec chaque échantillon de cheveux de référence est également enregistrée, une corrélation est établie entre les signaux enregistrés et l'état déterminé de la structure interne de la pluralité d'échantillons de cheveux de référence.
