Abstract

Appareil de repérage de la quantité de sébum. Cet appareil comprend un emetteur fournissant un faisceau modulé à une fréquence fixe, un récepteur ne mesurant que le flux reçu à la frequence de modulation de l'émetteur et un élément translucide préalablement appliqué de façon prédéterminée contre la zone de peau à étudier, et il est caractérisé par le fait que l'élément translucide est disposé en regard d'un organe réfléchissant tel qu'un miroir. Utilisable pour mesurer la quantité de sébum sécrétée par la peau.
