摘　　要：全光纤型侧向光学相干层析(OCT)探针由于兼具尺寸小和三维全周成像的优点,近年来受到了学术、工业界的广泛关注。文章通过对全光纤型侧向OCT探针的聚焦性能进行数值仿真,优化了探针的结构参数。基于优化的探针结构,针对反射器与GRIN光纤间随机横向位移引发的光功率衰落,进一步数值分析了探针套管尺寸及反射器位置对于探针鲁棒性的影响。All-fiber-type side-viewing optical-coherence-tomography(OCT)probe has attracted extensive interests in both academic and industry because of its ultra-small size and the ability of full-circumferential imaging.In this manuscript,the design of all-fiber-type sideviewing OCT probe is optimized for better focusing performance by numerical simulation.Furthermore,the robustness of the optimized all-fiber-type side-viewing OCT probe versus the size of probe tube and the position of reflector is numerically analyzed for the power fading resulting from the random transverse displacement between reflector and GRIN fiber.
