| 摘 要： | 石英光纤传像束在医疗诊断、工业设备探伤、电力设施监测、大视场成像等领域具有重要应用。本文利用溶胶-凝胶法在像元单丝间隙中引入吸收剂,解决了传像束光串扰难题。采用一次复丝工艺,制备出外径为600 μm、像元为15 000的石英光纤传像束,像元单丝直径约4.4 μm,分辨率约为113 lp/mm。结果表明,传像束无暗丝、断丝,成像清晰,无畸变,达到了商品化使用需求。

| Abstract: | Coherent silica fiber bundles have important applications in medical diagnosis, industrial equipment defects detection, high-voltage transformer winding monitoring, and large field optical systems. The sol-gel method is used to introduce absorbent into pixel monofilament gap, which successfully solves the problem of crosstalk in bundles. Silica fiber bundles with 600 μm outer diameter, 15 000 pixels, 4.4 μm pixel diameter, and resolution of 113 lp/mm were prepared by one-step multiple-fiber process. The results show that there are no dark or broken pixels, no distortion in bundles and the image is clear, which means the coherent silica fiber bundles meet the commercial use requirements. |
