A new form of interferometry combining high phase sensitivity and excellent mechanical isolation is proposed and demonstrated. These features arise from maintaining a probe and reference tone in the same medium under test at all times, their ultimate homodyne detection, as well as a novel method employing an optical programmable filter which is used to extract their relative phase difference. A compilation of studies performed to illustrate the applicability of the scheme to a range of measurements of optical propagation characteristics is presented. Measurements include the chromatic dispersion of SMF‐28 of lengths ranging from 1 m to 1 km, the nonlinear coefficient of highly nonlinear fiber and the phase transfer profile of an integrated optical ring resonator.

光谱差干涉法用于表征光学介质

提出并论证了一种新型的干涉测量技术，它将高相位灵敏度和出色的机械隔离性完美结合。这些特征源于始终在相同的被测介质中保持探针和参考音，其最终零差检测以及采用光学可编程滤波器的新型方法，该方法用于提取它们的相对相位差。进行了一系列研究，以说明该方案在一系列光学传播特性测量中的适用性。测量包括长度范围从1 m到1 km的SMF-28的色散，高度非线性光纤的非线性系数以及集成光学环形谐振器的相转移曲线。
