Abstract

We present a probe-based, phase-referenced low coherence interferometer in which the reference field is provided by a fiber end reflection. A gradient-index microlens focuses light onto a sample and collects reflected light. We use the probe interferometer to measure surface profiles of the compound eye of a housefly (Musca domestica) and measure nanometer-scale vibrations in a test sample.

摘要

我们展示了一种基于探针的、相位参考的低相干干涉仪，其中参考场由光纤端面反射提供。一个梯度折射率微透镜将光聚焦到样品上并收集反射光。我们使用该探针干涉仪测量家蝇（Musca domestica）复眼的表面轮廓，并测量测试样品中的纳米级振动。
