| 摘要 |
An optical sensor arrangement for measuring an observable including at least one light source for generating a first light component of a first frequency including a first mode and a second light component of a second frequency including a second mode orthogonal to the first mode, an optical resonator 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 the first and second modes, and a detector unit 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. |
