Abstract

PURPOSE: In order to perform the mode-distribution analysis which does not include the mechanical error, through two-dimensionally detecting the mode-distribution by way of using Fourier transformation-use convex lens, optical converter and so on, with respect to the angular distribution of Farfield of fiber emission-ray.
