Study on the characteristic of light transmission in a single-multimode fiber

摘要

Based upon the optical coherence superposition principle, a system to acquire light transmitted by a single-multimode fiber has been built. By collecting the optical interference images and using MATLAB software for analysis, the target light transmitted by a single-multimode optical fiber can be extracted from it. Thus, the transmission characteristics of light in a single-multimode optical fiber can be obtained, aiming to realize the direct transmission imaging through the multimode optical fiber by the compensation principle according to the change of phase in the transmission process and to provide technical support for the development of medical examination and medical devices in China.
