摘要： The invention relates to an optical sensor arrangement (1; 10; 40; 60) for measuring an observable comprising: at least one light source (2; 11, 12; 41, 42; 62, 63, 64) for generating a first light component of a first frequency comprising a first mode and a second light component of a second frequency comprising a second mode orthogonal to said first mode; an optical resonator (4; 17; 45; 69) having differing optical lengths for the first and second modes, at least one of the optical lengths being variable depending on the observable and a dependence of the respective optical length being different for said first and second modes, wherein the at least one light source is optically coupled to the optical resonator for feeding the two light components into the optical resonator; and a detector unit (6; 23 52; 74) being coupled to the optical resonator for coupling out the two light components and being configured for detecting a frequency difference between a resonance frequency of the optical resonator for the first mode and a resonance frequency of the optical resonator for the second mode. Furthermore, the invention relates to a method for measuring an observable by means of an optical sensor arrangement (1; 10; 40; 60) of this kind.

摘要： The invention relates to a method for detecting molecules of a particular substance by means of an optical sensor. This method comprises the steps of - bringing the sensor into contact with a fluid to be analyzed, - coupling light of a first wavelength (λ 1 ) into an optical resonator (3) of the sensor, the resonator (3) being covered at least partially with an active layer of a covering material for selectively adsorbing a group of substances, - coupling light of a second wavelength (λ 2 ) into the same resonator (3) or into a second optical resonator (3') of the sensor, the second resonator (3') being covered at least partially with an active layer of the same covering material - detecting, for each of the first and the second wavelengths (λ 1 ( λ 2 ), an optical signal coupled out of an optical path containing the respective resonator (3, 3'), - varying an optical length of the respective resonator (3, 3') or the respective wavelength (λ 1 ( λ 2 ) such that an interval comprising at least one resonance of the respective resonator (3, 3') is scanned, and - detecting a broadening of this resonance indicating an absorption of the light fed into the respective resonator (3, 3') by molecules accumulated at the active layer of this resonator (3, 3'). The invention also relates to an optical sensor designed for performing this method.
