Title (EN) OPTICAL PROXIMITY SENSING CIRCUIT AND METHOD FOR OPTICAL PROXIMITY SENSING
(FR) CIRCUIT DE DÉTECTION DE PROXIMITÉ OPTIQUE ET PROCÉDÉ DE DÉTECTION DE PROXIMITÉ OPTIQUE
Abstract:
(EN) In one embodiment an optical proximity sensing circuit (1) comprises an optical emitting device (10) which is prepared to send a signal (S1) having a wavelength of the invisible spectrum, a light conversion material (11) being prepared to convert a reflected signal (S2) into a detectable signal (S3), the reflected signal (S2) being a function of a reflection of the signal (S1) off a human user (20) and the detectable signal (S3) having a wavelength of the visible spectrum, and an optical receiving device (12) arranged apart from but in a visual range of the optical emitting device (10) and prepared to detect the detectable signal (S3) and therefrom provide a measurement signal which is a function of a distance between the optical proximity sensing circuit and the human user (20), wherein the conversion material (11) is mounted to the optical receiving device (12), and wherein each of the signal (S1), the reflected signal (S2) and the detectable signal (S3) is an optical signal.
(FR) Selon un mode de réalisation, l'invention concerne un circuit de détection de proximité optique (1) comprenant un dispositif d'émission optique (10) qui est préparé pour envoyer un signal (S1) ayant une longueur d'onde du spectre invisible, un matériau de conversion de lumière (11) étant préparé pour convertir un signal réfléchi (S2) en un signal détectable (S3), le signal réfléchi (S2) étant fonction d'une réflexion du signal (S1) d'un utilisateur humain (20) et le signal détectable (S3) ayant une longueur d'onde du spectre visible, et un dispositif de réception optique (12) disposé à distance mais dans une plage visuelle du dispositif d'émission optique (10) et préparé pour détecter le signal détectable (S3) et à partir de celui-ci fournir un signal de mesure qui est fonction d'une distance entre le circuit de détection de proximité optique et l'utilisateur humain (20), le matériau de conversion (11) étant monté sur le dispositif de réception optique (12), et chacun du signal (S1), du signal réfléchi (S2) et du signal détectable (S3) étant un signal optique.
