In this study, experimental demonstration of a static Fourier transform spectrometer (static-FTS), based on division of the spectrum into multiple narrowband signals, is presented. The bandpass sampling technique used in this novel spectrometer solves the Nyquist sampling rate limitations and enables recording of wideband spectrum in high resolution. The proposed spectrometer not only has the potential of operating in a wide spectral range, but also has a resolution potential better than 2 cm.
本研究提出了一种基于将光谱划分为多个窄带信号的静态傅里叶变换光谱仪（static-FTS）的实验演示。该新型光谱仪中使用的带通采样技术解决了奈奎斯特采样率限制问题，并能够以高分辨率记录宽带光谱。所提出的光谱仪不仅具有在宽光谱范围内运行的潜力，而且具有优于 2cm 的分辨率潜力。
