摘要

高精度相位测量是现代物理研究和应用的关键技术。本文提出了一种基于弱测量的自反馈测量方法，突破了传统弱测量技术灵敏度与量程相互制约的矛盾。该方法利用对输出光的光谱分布特性和波长位移的实时反馈和自动参考相位调制，实现了高灵敏度的目标相位测量（实验精度为10−5 rad）和测量范围的自适应扩展。实验验证表明，通过反馈控制，测量系统能始终保持高灵敏度的工作状态。

Self-feedback weak measurement for highly-sensitive, wide-range phase detection

High-precision phase measurement is a key technology for modern physics research and applications. In this work, a method of self-feedback measurement based on weak measurement is proposed to break through the contradiction of mutual constraints between sensitivity and range of traditional weak measurement techniques. By leveraging real-time feedback on the spectral distribution characteristics and wavelength shift of the output light and automated reference phase modulation, this method achieves high-sensitivity target phase measurement (with an experimental accuracy of

1 0^{- 5}

rad) and adaptive extension of the measurement range. The experimental verification shows that the measurement system can always maintain a highly-sensitive working state through feedback control.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
