Abstract

PURPOSE: To perform the measurement of the length and refractive index of an optical fiber of an unknown refractive index by determining the length of the optical fiber from the propagation ratio of light between the short length opetical fiber of the same quality as the optical fiber to be measured and the optical fiber to be measured.
