CA 2582699

Methods and apparatus for measuring an electromagnetic radiation response property associated with a substrate (210) are disclosed. The methods and apparatus generate electromagnetic waves (216, 218) and capture a portion of the generated waves after the waves pass through a first polarized filter (236), reflect from a substrate, and pass through a second polarized filter (204) arranged in a cross polar arrangement with respect to the first polarized filter. Digital data is determined from the captured electromagnetic waves. Based on the digital data, the customer is given certain choices and/or informed of certain personal care product recommendations.

L'invention concerne des procédés et un appareil permettant de mesurer une propriété de réponse de rayonnement électromagnétique associée à un substrat (210). Les procédés et appareil de cette invention permettent de générer des ondes électromagnétiques (216, 218) et de capturer une partie des ondes générées après leur passage à travers un premier filtre polarisé (236), leur réflexion à partir d'un substrat, et leur passage à travers un second filtre polarisé (204) disposé selon un arrangement de polarisation croisée par rapport au premier filtre polarisé. Des données numériques sont déterminées à partir des ondes électromagnétiques capturées. En fonction des données numériques, le client peut faire certains choix et/ou est informé de certaines recommandations concernant des produits de soin personnels.
