摘要：
We have constructed a simple Fourier Transform Spectroscopy system, and carried out performance measurement of our 640-GHz band SIS mixer devices. This system uses the identical quasi-optics to the one for heterodyne measurement, which allows a direct and quick comparison between FTS and heterodyne responses. With a room-temperature absorber for submillimeter source, instead of a high-temperature source such as Hg lamp, we successfully obtained interferogram with good signal-to-noise ratios. The frequency resolution is moderately coarse (Deltanu approximate to 17 GHz( due to a limitation on the travel length of scanning mirror for the interferometer, but we found it is useful to investigate broad-band characteristics of SIS mixers.
