Asymmetric Optical Resonator for High-Dynamic-Range Acceleration Detection

The patent applies asymmetry by designing an optical resonator with an asymmetric resonance lineshape, where the reflective element and optical fiber are positioned to create unequal slope characteristics on either side of the resonance peak. This asymmetric configuration enables dual-measurement methods that significantly improve acoustic wave detection precision and dynamic range, directly resolving the contradiction between measurement precision and device complexity by accepting increased structural complexity to achieve superior measurement capabilities

The patent employs parameter changes by systematically adjusting the positioning parameters of the optical fiber relative to the reflective element to optimize the asymmetric resonance lineshape characteristics. By carefully controlling parameters such as the distance and angular orientation, the system achieves high acoustic wave sensitivity while managing manufacturing precision requirements through defined parameter ranges that balance performance and manufacturability

The patent implements continuity of useful action by performing dual-wavelength measurements simultaneously or in rapid succession, allowing both wavelengths to be measured during a single acoustic wave event. This continuous measurement approach increases measurement productivity and throughput while minimizing signal processing time, as the system captures both wavelength signals in one continuous operation rather than requiring separate measurement sequences
