This study demonstrates a three-cavity multiplexing vibration-resistant Fizeau interferometry (TCM). The method injects a vibration-measurement pass (VMP), which utilizes three-cavity hybrid interference for the transmission of phase and vibration information, to the Fizeau phase-measurement pass (PMP). Moreover, the VMP is demultiplexed using the temporal difference of mixed fringes and synchronous phase-shifting phase extraction of difference fringe to obtain the vibration information, which is then used to calculate the measured phase combined with PMP. The feasibility and performance of the TCM are demonstrated experimentally. To the best of our knowledge, this is the first proposal of the TCM that not only solves the effect of vibration and null-fringe demodulation but also features a common path, simple testing process, and low system complexity.
本研究展示了一种三腔复用抗振斐索干涉测量法（TCM）。该方法将一个利用三腔混合干涉来传输相位和振动信息的振动测量通道（VMP）注入到斐索相位测量通道（PMP）中。此外，通过混合条纹的时间差和解调差分条纹的同步相移相位提取来对VMP进行解复用，以获得振动信息，然后将其与PMP结合用于计算测量相位。通过实验证明了TCM的可行性和性能。据我们所知，这是TCM的首次提出，它不仅解决了振动和零条纹解调的影响，还具有共光路、测试过程简单和系统复杂度低的特点。
