摘要: 石英光纤传像束因柔软易弯曲、抗电磁干扰等特点,在医疗内窥镜、工业探伤测量、新型光学系统等领域具有重要应用价值。本文利用COMSOL模拟计算软件,研究了光纤数值孔径、包层壁厚与能量泄漏率之间的关系,优化获得了填充系数高、串扰率低的光纤结构,研究了复丝拉丝工艺。结果表明,低温拉丝可降低易挥发元素F的溢出,有利于抑制缺陷的产生。采用一次复丝工艺,制备出单丝直径约4.4 μm、传像束外径0.4~0.6 mm、1 500~15 000像元、理论分辨率最高约131 lp/mm、可见光波段损耗0.1 dB/m的高分辨石英光纤传像束。石英光纤传像束端面无断丝、暗丝等缺陷,成像清晰、无畸变,成像质量良好,为石英光纤传像束的应用提供基础。

Abstract: Coherent silica fiber bundles (CSFBs) have important applications in the domains of medical endoscopy, flaw detection in industrial equipment, and novel types of optical systems due to their excellent flexible transmission of light and anti-electromagnetic interference characteristics. The relationship between the numerical aperture of optical fibers, cladding thickness, and energy leakage rate was investigated using COMSOL software, resulting in the optimization of a fiber structure characterized by a high filling factor and low crosstalk rate. The stack-and-draw process was studied. The results show that low-temperature drawing reduces the evaporation of the volatile element F, which is beneficial for suppressing the formation of defects. The high-resolution CSFBs are fabricated, featuring a single fiber diameter of approximately 4.4 μm, an outer diameter of the fiber bundle between 0.4 mm and 0.6 mm, a pixel count ranging from 1 500 to 15 000, the maximum theoretical resolution of approximately 131 lp/mm, and the optical loss of 0.1 dB/m in the visible spectrum by using a single stack process. The end face of the CSFBs exhibits no broken fibers or dark fibers, resulting in distortion-free imaging with high quality, thereby laying a foundation for the application of CSFBs.
