Abstract
A method based on Fourier transform to revise the non-linear spectrum attenuation of optical fiber used as a probe in a spectrum-measuring system is proposed in this paper. Spectral curves of a normal light source are measured by a spectrum-measuring system with and without the optical fiber probe, respectively. The generalized frequency spectrum (GFS) of these spectral curves can be calculated based on Fourier transform. From them, an optical fiber spectrum correction function can be obtained and the non-linear spectrum attenuation of optical fiber can be revised with the SCF. The experiment results show that the method has the accuracy of 1% and it is more accurate than the Ratio Method (RM) and the Weighted Ratio Method (WRM).
