Measurement of Refractive Index in Optical Fiber Prefabricated Stick with Scanning Method

摘要

The refractive index of optical fiber Prefabricated stick has great effect on the transmission characteristic of optical fiber. Consequently, it is necessary to measure the distribution of refractive index In this paper, a new method is proposed to measure the distribution of refractive index, which uses a thin light beam to scan the optical fiber Prefabricated stick.
