Abstract
We studied the optimization of common-path optical coherence tomography (CP OCT) sensitivity through an angled fiber probe. The magnitude of reference power derived from the tip of the fiber was optimized through careful selection of the polishing angle. We experimentally measured the signal-to-noise ratio (SNR) at different polishing angles to validate the effectiveness of this technique. We also obtained OCT images with the reference optimized CP OCT with more than 8 dB improvement in SNR.
摘要
我们通过斜角光纤探头研究了共路光学相干断层扫描（CP OCT）灵敏度的优化。通过仔细选择抛光角度，优化了来自光纤尖端的参考功率的幅度。我们通过实验测量了不同抛光角度下的信噪比（SNR），以验证该技术的有效性。我们还使用优化后的 CP OCT 获得了 OCT 图像，信噪比提高了超过 8dB。
