Abstract

Abstract Translated from French 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. Device for tracking the amount of sebum. This apparatus comprises a transmitter providing a modulated beam at a fixed frequency, a receiver measuring only the flux received at the modulation frequency of the transmitter and a translucent element previously applied in a predetermined manner against the area of skin to be studied, and it is characterized in that the translucent element is arranged facing a reflecting member such as a mirror. Can be used to measure the amount of sebum secreted by the skin.
