Paper Abstract

Analyzes the interferogram of a system for measuring the dispersion of CFBGs (chirped fiber Bragg grating) through Fourier spectrometric method. Theoretical representation of the interferogram is provided. A numerical model for simulating the interferogram is established under the common cognition that the recorded interfogram during the scanning of OPD (optical path difference) along the light beam axis is the sum of separate symmetrical interferogram of all quasi-monochromatic light components according to power. This analysis method will facilitate the analysis of interferogram of several interferometric systems in which the light transmits via a dispersive medium.
