The sensor system for the detection of chemical substances has a spiral optical waveguide (6) which produces an evanescent field penetrating into the adjacent medium (7), a light source (2) for coupling light into the waveguide (6), and a detecting circuit (9) for receiving light from the waveguide (6) and producing an output signal (11) reflecting the sensed chemical substance. The waveguide (6) has the form of a bifilar, non-crossing spiral. It consists of an incoming or decreasing spiral segment (12) and an outgoing or increasing spiral segment (13)continuously bound by a central semi-circular segment (14).

L'invention concerne un système de capteur permettant de détecter des substances chimiques. Ledit système de capteur comprend un guide d'onde optique en spirale produisant un champ évanescent qui pénètre dans le milieu adjacent; une source lumineuse permettant de coupler une lumière dans ledit guide d'onde; et un circuit de détection permettant de recevoir une lumière provenant dudit guide d'onde et de produire un signal de sortie réfléchissant la substance chimique détectée. Ledit guide d'onde possède une forme bifilaire en spirale sans croisement, et est composé d'un segment entrant ou décroissant en spirale et d'un segment sortant ou croissant en spirale reliés de manière continue au moyen d'un segment central semi-circulaire.
