【摘要】 传统的光纤探针的制备方法有两大类:热拉伸法和化学腐蚀法,但都不能满足理想的光传输效率。本文基于虹吸原理和动态大锥角化学腐蚀方法进行改进融合,成功制备出理想的光纤探针。并通过SPSS(statistical product and service solutions)数据分析软件从数理统计方面客观分析了该方法与静态化学腐蚀方法的显著差异。并设计另一实验系统,利用亚微米探针来获得高反射系数物体,如金属表面等的反射光信号。全文共分六章,具体如下: 第一章 绪论。介绍了一些目前常用的光纤探针制备方法,并对这些方法进行比较,分析其优点和缺点,以及本文研究目标、主要工作及创新之处等。 第二章 光纤探针制备及其信号探测理论。介绍大锥角光纤探针制备基本情况以及平头光纤探针对高反射系数样品表面反射光信号的探测的基本理论。 第三章 虹吸动态腐蚀大锥角光纤探针的制备。根据前人的研究,结合自己思路,设计出制备光纤探针的新方法,搭建该实验系统装置,并列出了一些实验所得的结果。 第四章 利用SPSS数据分析软件分析虹吸动态腐蚀大锥角光纤探针制备与传统静态腐蚀制备的光纤探针进行对比,从数量统计的角度分析该新方法的优势。 第五章 亚微米光纤探针对高反射物体的光信号探测。搭建实验装置,来进行未腐蚀的单模光纤和腐蚀过的亚微米光纤探针对高反射系数物体表面的光反射信号收集。 第六章 总结及展望。总结本文的主要工作,找出目前存在的问题,并探讨今后进一步深入研究和需要完善的方向。更多还原

【Abstract】 The traditional fabrication method of the optical fiber probe includes heat-pulling and chemical etching. But the two methods can’t obtain the ideal optical fiber probe. Based on siphon principle and dynamic large cone chemical etching method, link them together organically to fabricate the optical fiber probes. The optical fiber probes with ideal light transmission efficiency and high resolution can be easily obtained by the method. By the SPSS software, the distinct difference can be analyzed between the dynamic chemical etching based on the siphon principle and the traditional chemical etching method. We design another experiment system to obtain the reflection light signal of the high reflective sample, such as metal surface etc. The paper is composed of five chapters as follows:Chap. 1: Introduce the current fabrication methods of the optical fiber probe; compare the advantages and disadvantages with each other; the main objectives, main work of the paper, etc.Chap. 2: Introduce the theory of the optical fiber probe’s fabrication; the detecting theory of the optical fiber probe, including the flat single mode fiber probe.Chap. 3: According to other researchers findings, design my own new fabrication method of the optical fiber probe— The study on large cone optical fiber probes by dynamic chemical etching based on siphon principle. Lay out some results of the experiments.Chap.4: Make use of the SPSS (statistical product and service solutions) to compare the data of the cone angle and taper length between the large cone optical fiber probes by dynamic chemical etching based on siphon principle and traditional chemical etching method. Verify the advantage of the new method in view of statistical theory.Chap. 5: establish the experiment system to detect the light signal of the high reflective coefficient sample using sub-micron optical fiber probe and flat-headed single mode optical fiberChap. 6: summarize the main work of the paper; find the current difficulties and discuss the further improvement in the future.更多还原
