摘要

提出了一种基于感兴趣频率自适应调整短时窗宽度的自适应傅里叶变换算法。然后将该算法应用于使用太赫兹- tds获得的乳糖测量，并与标准固定窗谱图进行比较，观察到光谱对比度的提高。

Short-time Fourier Transform with Adaptive Windowing Size for THz-TDS

An adaptive windowing short-time Fourier transform algorithm is proposed where the width of short-time window is adaptively adjusted based on the frequencies of interest. The algorithm is then applied to lactose measurements acquired using THz-TDS and compared against the standard fixed window spectrogram where improved spectral contrast is observed.
