Abstract

We present the influence of alignment and the real properties of optical components on the performance of a two-detector homodyne displacement-measuring quadrature laser interferometer. An experimental method, based on the optimization of visibility and sensitivity, was established and theoretically described to assess the performance and stability of the interferometer. We show that the optimal performance of such interferometers is achieved with the iterative alignment procedure described.

摘要

我们展示了光路准直和光学元件的实际特性对双探测器零差位移测量正交激光干涉仪性能的影响。建立了一种基于可见度和灵敏度优化的实验方法，并从理论上进行了描述，以评估干涉仪的性能和稳定性。我们表明，通过所述的迭代准直程序可实现此类干涉仪的最佳性能。
