The powerdensityspectrum of an inner-phase-modulated optical fiber resonator is analyzed theoretically and experimentally, which is valid for any source coherence time.
Meaning: The self-correlation function and powerspectrumdensity Function of a power-typed signal compose a FT pair.
上式表明: 功率型信号的自相关函数与其功率谱密度函数构成傅立叶变换对。

This algorithm has utilized the signal to carry on the signal characteristic that Fourier includes in the density of the powerspectrum after Fourier transform.
