摘要
本文针对医用光纤在内窥成像,特别是荧光分子成像和拉曼光谱成像过程中产生的背景噪声问题进行了研究,提出了一种医用光纤背景噪声的光谱测量分析方法。结果表明,成像光纤背景噪声与光纤长度、激光功率均具有良好的线性关系。该研究结果对完善医用光纤的质量控制,引导生产企业提高医用光纤的质量,促进医用内窥镜技术的发展提供了有用的参考。
This paper focused on the background noise generated by medical imaging optical fiber during endoscopic imaging, especially fl uorescence molecular imaging and Raman spectroscopy. The paper proposed an analysis method that could conduct spectrum measurement of the background noise produced by medical imaging optical fiber. The results indicated that the background noise generated by medical imaging optical fiber was linearly correlated with the length of optic fibers and laser power. The results provide beneficial reference for improvement of quality control of medical optical fiber. The research can also guide enterprises in their effort of improving the quality of medical optical fiber, and thus serve as a reference for the development of medical endoscopy.
