本文以定性和实用的方式介绍了变迹和傅里叶变换光谱中相位信息的利用的几个方面。为了完整起见，提供了示例来说明应用更常见的变迹对光谱的影响。制定了相位信息的计算，并讨论和说明了相位谱中可用的信息类型。讨论了相位信息在相位校正中的使用，并给出了几个例子来说明结合某些变迹使用相位校正的必要性。说明了几种独特的变迹函数，包括对于分辨率增强非常有用的锯齿函数。最后，给出了工具化和自我变迹的例子。
This paper presents, in a qualitative and practical manner, several aspects of apodization and the utilization of phase information in Fourier transform spectroscopy. For completeness, examples are presented which illustrate the effects on spectra of applying the more common apodizations. The calculation of phase information is formulated, and the type of information available in phase spectra is discussed and illustrated. The use of phase information in phase correction is discussed, and several examples are presented which illustrate the necessity of employing phase correction in conjunction with certain apodizations. Several unique apodizing functions are illustrated, including a sawtooth function which is quite useful for resolution enhancement. Finally, examples of instrumental and self-apodization are presented.
