论文摘要
光学低碳反射仪能够明确测量样品对象中堆叠的，部分反射层的位置。它依赖于光源的低相干性，并且从机械运动阶段的位置读取绝对距离。我们展示了如何利用能量纠缠光子对的同时高和低相干性能，以直接使用参考激光波长校准OLCR扫描的位置尺度。在实验中，证明了1.6 \，NM和良好线性的精度。
Optical low-coherence reflectometry is capable of unambiguously measuring positions of stacked, partially reflective layers in a sample object. It relies on the low coherence of the light source and the absolute distances are obtained from the position reading of a mechanical motor stage. We show how to exploit the simultaneous high and low coherence properties of energy-time entangled photon pairs to directly calibrates the position scale of an OLCR scan with a reference laser wavelength. In experiment, a precision of 1.6\,nm and good linearity is demonstrated.
