We demonstrate the operation of a Fourier transform spectrometer that operates by sweeping the pulse repetition frequency of an electro-optic frequency comb. Incorporating a length-imbalanced interferometer, this single-comb system is analogous to a conventional dual-comb system, but with a greatly simplified design. The functionality of the spectrometer is demonstrated via the high-resolution spectrum measurement of an ${\mathrm{H}}^{13}{\mathrm{C}}^{14}\mathrm{N}$ reference gas cell.

通过单个电光频率梳的重复频率扫描进行傅立叶变换光谱

我们演示了通过扫描电光频率梳的脉冲重复频率进行操作的傅立叶变换光谱仪的操作。该单梳状系统结合了长度不平衡的干涉仪，类似于传统的双梳状系统，但设计大大简化。光谱仪的功能通过高分辨率光谱仪对仪器进行了演示。${\mathrm{H}}^{13}{\mathrm{C}}^{14}\mathrm{ñ}$ 参考气室。
