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.
