Abstract

We propose and demonstrate a method of real-time dispersion compensation suitable for scanning interferometry and optical coherence tomography. Static grating tilt in a scanning frequency-domain optical delay line is shown to produce dispersion that is linearly proportional to scan position, and we use this property to achieve depth-dependent dispersion compensation during an interferometric scan through a dispersive sample.

摘要

我们提出并演示了一种适用于扫描干涉测量和光学相干断层扫描的实时色散补偿方法。结果表明，扫描频域光学延迟线中的静态光栅倾斜会产生与扫描位置成线性比例的色散，并且我们利用这一特性在通过色散样本进行干涉扫描期间实现深度相关的色散补偿。
