| Outline of Final Research Achievements |
In this research, we demonstrated improved spectral resolution by overcoming the time window size limitation using a mode-locked terahertz (THz) or near-infrared (NIR) pulse train as precisely periodic pulsed radiation in discrete Fourier transform spectroscopy (dFTS). Since infinitesimal resolution can be achieved at harmonic components of its repetition frequency 1/T when the time window size is exactly matched to the repetition period T, a combination of dFTS with a spectral interleaving technique achieves a spectral resolution only limited by the spectral interleaving interval.
