A theoretical analysis of the use of a fiber bundle in spectral-domain optical coherence tomography (OCT) systems is presented. The fiber bundle enables a flexible endoscopic design and provides fast, parallelized acquisition of the OCT data. However, the multimode characteristic of the fibers in the fiber bundle affects the depth sensitivity of the imaging system. A description of light interference in a multimode fiber is presented along with numerical simulations and experimental studies to illustrate the theoretical analysis.
本文对光谱域光学相干断层扫描(OCT)系统中光纤束的使用进行了理论分析。光纤束可实现灵活的内窥设计,并能快速、并行采集OCT数据。然而,光纤束中光纤的多模特性会影响成像系统的深度灵敏度。本文给出了多模光纤中光干涉的描述,并结合数值模拟和实验研究来说明理论分析。
