我们描述了一个封闭的形式的方法进行Kramers-Kronig(KK)变换,可以用来快速,可靠地检索的相位,从而共振虚部,从宽带相干反斯托克斯拉曼散射(汽车)光谱与非平坦的背景。在这种方法中,我们将频域数据变换到时域,执行确保满足因果关系标准的操作,然后变换回频域。事实上,这种方法处理因果关系在时域中,使我们能够方便地占光谱变化的非共振背景汽车作为响应函数与有限的上升时间。有限频率范围数据的KK变换伴随着相位误差。在这里所示的示例中,该相位误差导致检索的谐振光谱中的小(<1%)误差。
We describe a closed-form approach for performing a Kramers–Kronig (KK) transform that can be used to rapidly and reliably retrieve the phase, and thus the resonant imaginary component, from a broadband coherent anti-Stokes Raman scattering (CARS) spectrum with a nonflat background. In this approach we transform the frequency-domain data to the time domain, perform an operation that ensures a causality criterion is met, then transform back to the frequency domain. The fact that this method handles causality in the time domain allows us to conveniently account for spectrally varying nonresonant background from CARS as a response function with a finite rise time. A phase error accompanies KK transform of data with finite frequency range. In examples shown here, that phase error leads to small (<1%) errors in the retrieved resonant spectra.
