摘要

提出了一种基于两个相干频率梳的新型FTIR光谱。全电子干涉图记录允许同时进行幅度和相位光谱，并以100 /spl mu/s(预期为1 /spl mu/s)的速度进行快速光谱采集，实现单事件分析。衍射限制传播建议用于遥感，经典显微镜和散射型近场显微镜。

Coherent-beam FTIR spectrometer with no moving parts

A novel type of FTIR spectroscopy based on two coherent frequency combs is demonstrated. All-electronic interferogram recording allows simultaneous amplitude and phase spectra, and fast spectrum acquisition in 100 /spl mu/s (1 /spl mu/s anticipated), enabling single-event analysis. Diffraction-limited propagation suggests use in remote sensing, classical microscopy and scattering-type near-field microscopy.
