我们报告的数值分析梯度折射率（GRIN）透镜为基础的光学相干断层成像探头，以获得最佳的设计参数。长和短的工作距离探头与一个小的焦点被认为是。在每个模型中，工作距离和束腰的特点和比较不同的值的长度和折射率的探头组件。我们还探讨了外管和样品介质的折射率的影响。数值计算结果表明，GRIN透镜端面最大光束直径和聚焦角的调整对确定探头的光学性能参数至关重要。(C)2010国际光学工程学会，[DOI：10.1117/1.3523374]
We report the numerical analysis of gradient index (GRIN) lens-based optical coherence tomography imaging probes to derive optimal design parameters. Long and short working distance probes with a small focal spot are considered. In each model, the working distance and beam waist are characterized and compared for different values of length and refractive index of the probe components. We also explore the influence of the outer tubing and refractive index of the sample media. Numerical results show that the adjustment of the maximum beam diameter and focusing angle at the end of the GRIN lens surface is very important for determining the optical performance parameters of the probe.
