摘要： An optical sensor arrangement for measuring an observable, the arrangement including an optical resonance circuit including at least a first and a second optical resonator, each of the optical resonators including an entry port for coupling light into the optical resonator and a drop port for decoupling light from the optical resonator. The first and second resonator are configured such that only a portion of the first and second resonator detects the presence of the observable, a size of the portion of the first resonator being different from a size of the portion of the second resonator. The optical resonance circuit further configured to be coupled to a light generation circuit and to a detector unit for detecting light.

摘要： A sensor arrangement including a light source, a first optical element, a second optical element, a first photo detector, and a second photo detector. The light source is optically coupled to the first optical element that is optically coupled to the second optical element. The first photo detector is optically coupled to the first optical element for detecting a first component of the part of the light which is not transmitted by the second optical element, and the second photo detector is optically coupled to the second optical element for detecting a second component of the part of the light which is transmitted by the second optical element. One of the first and the second optical elements is an optical filter and the other is a sensor element, where the sensor element or the filter is tunable.
